1960s Paymaster series S-1000 check writer w/key mid century office

Vintage machine age Paymaster S-1000 series mechanical writer with the original locking key. This machine measures about 10 1/2" long and 7 1/4" high.

This has some wear and flaking to the industrial gray paint in areas. This will probably need cleaning and a tune-up (as well as new ink pads) to run.
