Bought these two items a little while ago. Both are from the 1920's-30's.
The key board is complete with all the original keys with the correct corresponding numbers on them. I believe there are three master keys that fit multiple locks.
The tin litho policeman is a killer early piece with the original box. It is designed to be mounted in the rear window. When the brakes are applied the forward inertia causes a weight to swing forward causing the policeman's arms to swing out. Upon accelerating the weight falls back and the arms swing back.
Had to pay a kings ransom for that policeman!
