vintage metal file box, mid-century machine age locking office file / cash box

Vintage Mystrong steel file organizer box, with working lock and key on separate interior cash box type compartment. (We have no key for the outside lock, on the lid.) This has a little wear and scuffing to the original green drab finish, but works fine overall, not out of shape. Measures 12 1/2" x 12" x 5 1/2" over the exterior dimensions.
