Up for SALE is a Steel Lever Padlock. Stamped on front is PATENT "A". The lock does look home made in a way. The key is hand made. At first I thought this was German origin or European… Now after looking at it I’m not sure. I don’t think it’s a patent lock but not sure why it would be Stamped PATENT A
Brass Key works great.
Size is approx. 4 ½ x 3 x ¾
