I'm trying to date my Pico Adding Machine by Precision Instrument Co., Cliffside Park, N.J. It is an abacus. It is pocket size, about 3 inches by 4 inches, with the pen-like tool to move the number gears. It also has a swing out wire stand attached to the back to stand it up like a picture frame, and a red leather case. Can anybody help me? Thanks, Rick
