Sry for keeping you waitin Brian. Works been a pain latest few weeks.
I was looking for a detail that should be on the dial but have been where the patent was engraved, but i cant find it. Also the dials on your lock looks similar to those created in the late 1880s, so im guessing thats when ur locks from aswell.
Is the case of the first lock you posted openable? Are there any details on the outside worth mentioning?
