As Duke said, there's a lot of speculation that it could possibly might be a Blacklock, but as far as I know there is no definitive evidence out there of what the Blacklock's looked like-- from what I've read it was one person making a guess and then it spread like wildfire. I've seen these commonly referred to as Initial Skillets, due to the the 2 large raised letters on the back. Either way, I'd pick that up for $17.50 no questions, as they are interesting, distinctive, have a certain mystique around them, and of course seem to be well made.
