Tested and Works

Not sure but it might be from the 1920's (before WWII)

2 of the 4 rubber feet on bottom

1 of the 2 screws on the back

3 Number Key Plastic Top Pieces (two 1's and a 7) - Keys obviously still work without their plastic caps

1 Plastic Key on the upper row next to the ND key

See Pictures

If the circle above the number on the front edge is for a reset the overall total, I do not have the key that does that.

Perhaps this was used in a bank and the owner would reset them or something like that. I am only guessing.
