Wagner Ware Sidney -O- No. 12 Cast Iron Skillet
SSC MUSEUM COLLECTION
Catalog No. SSC-WGNR-SKL-012
Cast Iron Skillet | No. 12 | Center Logo | Sidney, Ohio
c. 1922–1924 • Wagner Manufacturing Company • Sidney, Shelby County, Ohio
Interior cooking surface of the Wagner Ware Sidney -O- No. 12 skillet, showing the full 11¾-inch cooking floor, scalloped pour spouts on the rim, and the classic Wagner teardrop hanging loop on the main handle. The deep even seasoning reflects a fully restored piece.
The Wagner Ware Sidney -O- No. 12 in the Steve’s Seasoned Classics collection is not simply a large, scarce skillet. It is a dated document. The placement of the stylized Wagner Ware Sidney -O- logo at the center of the base — rather than the standard 12 o’clock position — combined with the complete absence of a catalog number, places this piece in the narrowest datable window in the entire Wagner Ware Sidney -O- skillet series: approximately 1922 to 1924. This is the earliest configuration in which the iconic stylized W logo appears on a Wagner skillet, before catalog numbers were introduced and before the logo settled into its permanent position.
A No. 12 is already a scarce size in the Wagner line — produced in lower volume than the everyday domestic sizes, encountered infrequently in the market, and requiring deliberate pursuit to acquire in collection-grade condition. A No. 12 with the center logo and no catalog number narrows that field further still. This piece represents the oldest datable stylized logo configuration in the SSC Wagner Ware Sidney -O- complete skillet set.
The cooking surface is exceptionally clean, the seasoning is deep and even throughout, the markings are fully legible, and there are no cracks or repairs. The heat ring on the base is present and consistent with pre-1935 manufacture. The piece has been professionally restored to collection-ready condition.
The Center Logo: Dating a Narrow Window
Base of the No. 12 skillet. The stylized Wagner Ware Sidney -O- logo — the looped W above SIDNEY and -O- — is positioned at the CENTER of the base rather than the standard 12 o'clock position. The size number '12' appears below the logo. No catalog number is present anywhere on the base, confirming manufacture in the c. 1922–1924 window before Wagner's numbering system was adopted.
The position of a Wagner Ware stylized logo on a skillet base is one of the most reliable dating tools available to the collector. For the first thirty years of Wagner’s history the trademark consisted of WAGNER in block or arc lettering with SIDNEY O. below, and that mark moved freely around the base — centered, high, low — without a fixed position. When the stylized looped W was introduced around 1922, the same fluidity continued. The logo appeared at varying positions on the base before eventually settling permanently at the 12 o’clock position.
The Cast Iron Collector’s trademark reference documents the center-positioned stylized logo in two distinct configurations: pieces from approximately 1922–1924 carrying a heat ring and size number only (no catalog number), and pieces from approximately 1924–1935 carrying a heat ring and catalog number. This No. 12 belongs to the first and earlier of those two groups. The stylized W is centered on the base. The size number 12 appears below it. There is no catalog number anywhere on the piece.
Wagner adopted its four-digit catalog numbering system in 1924. The formula for regular skillets was 1050 plus the size number: the No. 12 would have become catalog number 1062. The complete absence of that number — or any four-digit number — on this base is not an oversight or a damage artifact. It is a chronological marker. This piece was cast before 1924. It is the earliest datable stylized logo configuration in the SSC collection.
The No. 12 Skillet: A Scarce Large Size
Profile view of the No. 12 showing the 2¼-inch sidewalls, the broad cooking floor, and the overall form of the piece. The absence of an assist handle is correct for the No. 12 — that feature appears on the No. 13 and No. 14 only.
At 13¾ inches across the top rim and 11¾ inches at the cooking floor, the No. 12 is the largest standard Wagner skillet produced in both heat-ring and smooth-bottom configurations. Sizes 13 and 14, larger still, were made only with heat rings. The No. 12 is therefore the transition point — the last size for which Wagner produced both variants — and examples in either configuration are scarcer than the everyday sizes below them.
The No. 12 was not a standard household pan. At nearly 14 inches across the top rim, it exceeded the cooking zone of most domestic stove eyes and was aimed at larger households, farm kitchens, and light institutional use. Its position in the line — large enough to be unusual but still manageable without an assist handle — made it a specialized acquisition even when new, and its relative scarcity in the market today reflects that original production profile.
The absence of an assist handle on the No. 12 is correct and consistent across the entire production run of this size. Assist handles are a feature of the No. 13 and No. 14 only, where the weight and diameter made two-handed control a practical necessity. The No. 12, though large, was designed for single-hand use with the teardrop-loop main handle.
Wagner Manufacturing Company: Sidney, Ohio
The Wagner Manufacturing Company was founded in June 1891 by brothers Milton M. and Bernard P. Wagner in Sidney, Shelby County, Ohio. The foundry opened with twenty employees and within three months was melting approximately 9,200 pounds of iron daily. R.O. Bingham, a veteran of the Marion Stove Works and the Sidney Manufacturing Company, joined as plant superintendent and proved a prolific designer. Wagner introduced nickel-plated hollow ware in 1892 and became one of the first American manufacturers of cast aluminum cookware in 1894. By the early twentieth century the Sidney plant had grown to 160,000 square feet with a staff of 300. The Sidney Daily News described it as “the largest Holloware Plant in the World.”
About 1914, Wagner began marketing its products under the combined ‘Wagner Ware’ brand name. Around 1922 the iconic stylized W was introduced — the large looped letterform serving double duty as the first letter of both ‘Wagner’ and ‘Ware’ — positioned above SIDNEY and -O-. In its earliest incarnation the logo was not fixed in position; it appeared at center, high, and varied locations on the base. In 1924 Wagner adopted a four-digit catalog numbering system and the logo gradually settled into its standard 12 o’clock position, where it remained through the end of the collector era in 1959.
The original Wagner family divested between 1946 and 1952, selling to the Randall Company of Cincinnati. In 1957 Wagner’s Randall division acquired Griswold Manufacturing. Textron acquired Randall in 1959, marking the accepted end of the collector era with the removal of SIDNEY -O- from the logo. The Sidney foundry closed permanently in July 1999. The factory building was demolished in June 2023.
Markings Analysis
Bottom profile of the No. 12 showing the heat ring and 2¼-inch sidewall depth. The heat ring is present and consistent with pre-1935 manufacture. No. 12 smooth-bottom examples exist but are distinctly less common than heat-ring versions.
The markings on this piece tell a precise story. The stylized Wagner Ware Sidney -O- logo is positioned at the center of the base — not the 12 o’clock position that became standard and remained standard from the mid-1920s through 1959. The size number 12 appears below the logo. No catalog number is present. No MADE IN USA marking is present.
Each of these absences is informative. The absence of a catalog number places manufacture before 1924. The absence of MADE IN USA places manufacture before 1959. The presence of the stylized W places manufacture after approximately 1922. The center logo position is documented by the Cast Iron Collector as characteristic of the 1922–1924 period for pieces carrying only a heat ring and size number. All evidence converges on a manufacture date of c. 1922–1924 — the opening years of the stylized logo era and the earliest datable configuration in which the iconic Wagner mark appears.
The heat ring is present and intact. Unlike the No. 13 and No. 14, which were never produced without heat rings, the No. 12 was eventually produced in smooth-bottom form after approximately 1930–1935. The heat ring on this piece is therefore both chronologically consistent with its pre-1924 date and a distinguishing feature from the later smooth-bottom No. 12 examples.
Handle
Handle detail of the No. 12, showing the classic Wagner teardrop hanging loop. The handle is intact and clean throughout, with the deep even patina of the restoration visible on all surfaces.
The main handle terminates in Wagner’s classic teardrop hanging loop — the open-eye form characteristic of the Sidney -O- skillet line across all logo eras. The handle is intact with no cracks or losses and shows the consistent deep patina of the restoration throughout. No size mark is visible on the handle top in the photographs; any such marking, if present, would be confirmed on in-hand examination.
The No. 12 carries no assist handle. This is correct for the size. The double-loop assist handle is a feature reserved for the No. 13 and No. 14, where the weight and diameter made two-handed control a working requirement. The No. 12, though the largest size to transition to smooth-bottom construction, was engineered for single-hand use.

Why This Piece Matters
The Wagner Ware Sidney -O- No. 12 with center logo matters first as a chronological document. The center position of the stylized W, combined with the absence of a catalog number, dates this piece to the very opening years of the logo that defined Wagner’s identity for nearly four decades. Somewhere between 1922 and 1924, a foundry worker in Sidney, Ohio poured the iron for this pan and pressed that newly designed looped W into the center of its base. The catalog number system that would follow in 1924 would eventually standardize the logo’s position at 12 o’clock. This piece was made before that standardization. It is an artifact of the moment the mark was still finding its place.
It matters as a scarce size in a complete set. The No. 12 appears in the market less frequently than the No. 6, No. 8, or No. 10. A No. 12 in excellent restored condition with a center logo and no catalog number is a substantially more specific find than any standard No. 12 in the standard logo position. Within the SSC complete skillet set, this piece carries the oldest datable logo configuration of any numbered skillet in the collection.
It matters because the No. 12 is the largest size in the Wagner line to have been produced in smooth-bottom form — and this example carries the heat ring that places it before that transition. It sits at the boundary between the eras: large enough to have needed two more decades of production before Wagner’s engineers decided it could be made without the raised ring, but cast here in the years before that decision was made.
The iron endures. The markings tell the truth. The story deserves to be told.
