Vintage Comptometer – Adding machine.
It is not old dive gear but is is a lovely antique adding machine and was in an old dive shop I used to own so it does have a diving history.
This adding machine was manufactured by Felt & Tarrant Mfg. Co in Chicago.
I think this particular machine was built around the 1930s to 1940s but I am not positive.
Serial number is 253270.
It is in used condition but still a nice item.
