Remington Rand Model 20 Type 321 Card Sorter, for Use with a Remington Rand Model 3 Tabulating Machine

Description
This electrically powered machine is part of a Remington Rand punched card data processing system. The sorter could arrange Remington Rand punch cards into any sequence, usually a numerical, alphabetic, or alphanumeric sequence. It has a gray metal exterior and several bins, arranged horizontally, into which the cards are sorted.
A mark on a tag attached to the machine reads: Model 20 Type 321. A mark on another tag reads: A.F.L.-C.I.O (/) HEADQUARTERS (/) 38. Another mark reads: Remington Rand.
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. According to Diebold, in 1956 a 321 automatic sorter that sorted 420 cards per minute sold for $3,452 and rented for $50 per month.
