Marchant Calculating Machine Model

Description
This is a model designed to demonstrate “simplified multiplication” on a Marchant calculating machine. It has a rectangular wooden base and a metal frame. The single bank of keys has nine square gray keys on it. The operating handle is on the right side. The shape of the keys suggests that this model is from the mid-1960s, when multiplication keys on SCM Marchant models such as the CFA were square. However, the rest of the mechanism, particularly the wooden base, suggest an earlier date.
A metal tag attached to the base reads: SIMPLIFIED (/) MULTIPLICATION. It also reads: M. A final mark reads: U.
