Unknown Safe Lock 1

Unknown maker, year, and patent (if any)

This lock is fairly simple in both its construction and operation. To unlock the lock, the key is inserted and turned clockwise 90 degrees. The 90 degree turn helps block access to the levers to make picking harder. The levers then fall into a cutout on the keyway where they impact the key bitting. With the proper key in place, the slit in the bottom of the levers lines up with the vertical bar. The knob is then turned which lifts the vertical bar and draws the bolt back to unlock. In this state, the vertical bar does not drop back below the levers, leaving the key trapped in the lock. When locked, the vertical bar falls below the levers, allowing the keyway to turn 90 degrees counterclockwise to extract the key.

The lock does have a unique flower or star shaped knob, so hopefully someone will recognize it and be able to identify its maker or what company might have used it on their safes. The only marking on the lock is the number 2 on one of the internal pieces. Any information you might have would be greatly appreciated.
