The Perin & Gaff Mfg. Co. Susan R. Knox Patent Crank Fluting Iron

Buckeye Iron & Brass Works 2” Fig. 671 Cleanout Cap
This cast iron cleanout cap was produced by Buckeye Iron & Brass Works of Dayton — the foundry the Wright Brothers walked into when they needed an aluminum crankcase for the engine that would fly at Kitty Hawk. Some of the best stories in American cast iron are not on skillets. They are on the workpieces that built the infrastructure.
