Old combination lock. It is 1 3/4" wide and 2 3/4" from the top to the bottom. On the back it has: MADE IN USA PAT. NO. 2047102. This patent No. indicates it was made between 1936 and 1937. I do not have the combination. It is rusty, but it is surface rust, not deep. Shipping will be $2.75 for first class.
