Remington Rand Type 312-1 Interpreter, for Use with a Model 3 Remington Rand Tabulating Machine

This machine, part of a Remington Rand punched card system, is roughly the size and shape of a corner mailbox (but much denser) and has a gray metal exterior. It interpreted the punched holes in a 90-column punched card and registered this interpretation by printing numbers and letters along the top of the card. The card feed is at the center front and the card receiver, at the back. A door on the right side opens to allow one to remove the wiring unit chamber. The wires sense whether there is a hole in a given position of a card, and determine what is printed and where by the printing unit below it.
A tag attached to the machine reads: Model 3 (/) Type Number 312-1. Another tag attached to the machine reads: A..F.L.-C.I.O (/) HEADQUARTERS (/) 40.
Three loose pieces are with the machine.
This machine is part of a system owned by the American Federation of Labor and Congress of Industrial Organizations, an important American labor union formed by the merger of the A.F.L. and the C.I.O. in 1955.
