The Red Book, Lodge section, shows what the authors believe a Blacklock skillet might have looked like. Given the timeframe and the fact that Lodge Mfg. Co. succeeded Blacklock so soon after its demise, the expectation would be that it would have had an outside heat ring, been side-gated, with a raised size number atop the handle, and a molder's mark letter on the bottom at 6 o'clock. Recently published collector research has attempted to add a somewhat wavy, smashed looking handle reinforcement rib to the mix as a characteristic indicative of Blacklock.
