Burroughs Experimental Adding Machine

Description
This model for a ten-key printing electric adding machine has a metal mechanism with tan and dark tan plastic keys and a rubber carriage and rubber feet. It adds eight digit numbers, and has a 10-column printout (one column may be of symbols). There is a block of nine gray plastic number keys with a 0 bar below. Two dark brown, square function keys to the left of the digit keys are marked “C” and “X.” Three similar keys rightt of the digit keys are marked “ST”, “*(/)TOT”, and “-.” A fourth function key on the right is unmarked. There is a place indicator, a 2-1/4” carriage, and a black ribbon. No cover or cord.
A red tag attached to the machine reads: PATENT DEPARTMENT (/) #161. A metal tag on the left side reads: 31794A.
This model, along with 1982.0794.28, was #161 in the collections of the Patent Division of Burroughs Corporation. The accession file suggests that this was the invention of Althans, presumably Emile H. Althans of Burroughs.
