I have a 1950s Mosler Vault door and frame that is installed in a former bank. The bank used it until last month, it works, timer works, also 237 safety deposit boxes various sizes, 90 percent have keys. Also, have a 1908 Victor cannonball safe that works, timer works, the bottom horizontal combination does not work but will shut. They are located in Hindsville, Arkansas, USA. Thanks for reading and responding. I will try to get pictures in a few days.
