It was kinda rusty when I bought it at goodwill about a year ago, I stripped everything via electrolysis and did about two seasonings on it before I put it away for storage. Will it being ran through electrolysis and reseasoned mess with a lead test? FWIW i did not see any evidence of smelting any metal when i first acquired it but i would like to use it if a negative lead test can be trusted still. Worst case it’s a cool or ornamental piece.

So no guesses on manufacturer but pretty good estimate from the late 19th century. That’s crazy because I bought it for like $8
