I picked up and L.C. Smith 1904 0 grade hammer double, With differing hammers, and when I say differing I mean they are the same hammers standard from the company with differing knurling engraving on the tops of the hammers. The top right hammers is the standard diamond checkering while the left top hammer is a bullseye pattern of round rings increasing from smallest to largest... The design of the hammers are Identical in shape and size just the casting being different, I was just wondering if anyone else had run across this yet or maybe if it was standard on some of the L.C. 's.. Thanks A.J.
