Columbus Hollow Ware No. 10 Skillet

The No. 10 is the pivot piece of the SSC Columbus Hollow Ware set — where the domestic cooking story gives way to large-scale provisioning, and where the "S" mark research takes its most significant turn. Present on the No. 8, absent on the No. 9, and confirmed again here on the No. 10, the subsidiary mark is clearly not a batch code or a uniform production identifier. It follows a size-selective pattern that only a five-piece matched set from a single provenance could reveal — and SSC is now on record with the comparative documentation to prove it.
