Cute Ratner lock

Cepasaccus

I do have this Ratner lock. 7 levers, one have which has a smooth edge. The cover plate is steel. One of the two screws has a dot, but I didn’t find the corresponding dot on the case. The key has the number 71053 stamped and on he case somebody had probably scribbled the same number with pencil or so.

Is it possible to date this lock? Thanks

Lock number 71053 was made in 1966. Probably known as a C12-52
