Picked it up for a song recently. I suspect it to be a BSR but it's kind of weird. Also, why is it so clean and skinny? It looks like aluminum but it's labeled as CI.
This is a nickel plated griswold. Nickel plating is something they did at the factory on some skillets because there was some section of the population back then who were obsessed with nickel plating.
As far as the center logo being gone, there was a time when natural gas piped to the home wasn’t as refined and still had sulfur in it and during combustion it produced a minute amount of sulfuric acid which over time caused pitting in the bottom of skillets
I’ve been at this for over a decade and while I’m am by no means an expert you’d be surprised at how quickly you’ll start noticing subtle differences and eccentricities in pans from different manufacturers.
This pan for example is definitely a griswold. One can tell from a mile off from the letter typeface on the handle which is classic griswold. Seeing the bottom text and typeface sealed it. Hope this helped :)
I just ground down my lodge, and it's not difficult to get any level of shiney. It's just a matter of moving up in grit - I started with 24, then worked my way up to 220. It was fun.
That's a Griswold, The bottom is in bad shape, but it probably still cooks well (after getting it cleaned up and seasoned). Similar pan but different size
