This punched card machine, called a collating reproducer, mechanically feeds and reads punched cards from two hoppers for determining whether one card is greater than, equal to, or less than the other. It combined two sets of cards in numerical order. If the sequence control is turned off, it can be used to reproduce a set of cards. One card hopper is at the top front, the other at the middle front. Segregated cards went into receivers at the back.
A mark on a tag attached to the machine reads: Model 3 Type 315-1. A mark on a second card reads: A.F.L.-C.I.O (/) HEADQUARTERS (/) 39.
According to Diebold, this device sold for $12,000 in 1956, and rented for $150 monthly.
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.
