Aw David. That skillet. There's been speculation when skillets like yours have surfaced in the past, but no documentation. I do wish we could compare it side by side with a BS&R 14. If exactly the same as a BS&R 14, that may lend credence to the theory it was made from a repaired BS&R pattern. If slightly smaller than a BSR 14, that may lend credence to the theory that someone used a BSR skillet, modified the handle and used that as a pattern.
So what I'm saying is as far as I known, the maker is unknown. Did that clear it up?[ch128513]
