I am not convinced that the lock is stamped "Blount Co." If you look closely at the stamping, it appears to have some different letters in it. I'd surmise that it might have a different, more eastern name on the lock plate that was hard to read, and they "guessed" that it said Blount Co. If in fact it is stamped Blount Co., then it raises some questions about the lock. Shelby Gallien
