What am I getting myself into? Lock ID help, please
Here are the photos I was provided. I was lucky to get a shot of the under side of the door before the seller went and locked the door in the safe (combo unknown) while answering my questions. Grrr. I thought, O.K. I can try to manipulate it any way. The outside looks like a typical S&G, with a typical spring fence type changing index position to the left of the opening index. I'm sure I can get it open......
But, the photo of the under side has me wondering...
This looks an awful lot like my S&G friction fence C87 lock (note the same shaped flat, brass case cover, and positions of the screws, change key hole, and indexing pin (across from the change key hole)). It looks like a match.....
So, here's the thing. The C87 friction fence lock has the changing index to the right of the opening index on the dial, by necessity, like this....
My questions are, did other S&G locks share the same lock case configuration during that period? Especially note the positions of the screws, change key hole, and single indexing pin. I'm hoping for a 6700-series type, spring fence lock here!
OR, is it more likely that someone installed a C87, while keeping the 6700-series type dial ring in place? (the diameters are compatible)
