Looking for help to ID this lock. It is about 3 ⅝ L X 2 ⅝ W X 1 ¼ D. The back has Desh Lock and Bargular Proof on it and the front is also Desh Lock, Public Metal Industries, Aligarh, on the keyhole cover Strong Machinery registered #73461. This number is also hand stamped across the case seam along with 1957.
Any info and value of this one would be greatly appreciated.
Terry
