Description
This full-keyboard printing electric adding machine has a tan steel frame and eight columns of tan and brown square plastic keys. To the left of these is a column of keys with the numbers 71 through 79 (there is a 65 instead of a 75), presumably denoting years. Left of this is a column with four keys for the months of quarterly statements (DEC, SEP, JUN, and MAR) and two keys labeled MR and CHK respectively. There are function bars and keys to the right of the number the keys.
Above the keyboard are four number wheels. Behind them is a two-colored ribbon and a printing mechanism, an adjustable wide carriage, and narrow paper tape. The type wheel for months has all 12 months on it. The ribbon and its spools are covered, with screws holding the covers in place. Plastic knobs at the ends of the carriage are rotated to advance the platen. On the right side of the machine is a place for inserting a crank, although there is no crank. At the back on the right side is a lock for the machine, with the key in it. There also is a lock at the left front of the machine.
The machine is marked on the front: Burroughs. The serial number, on a metal tag on the back of the machine, is: P366728D It is from after 1960. Another metal tag on the back of the machine is marked: SERIES P (/) BURROUGHS CORPORATION (/) DETROIT, MICHIGAN MADE IN U.S. America.
