SCM Marchant Adding Machine Experimental Model

<< >>
Description
This is a model for a ten-key printing electric adding machine, most probably made at or for SCM Marchant. It has a metal mechanism (there is no case), nine gray round plastic digit keys arranged in a block, and darker gray 0 and total keys. There are seven additional key stems as well as three double key stems for bars. None of these have covers. Behind the number keys is an 11.5 cm. carriage for the paper tape, as well as a 2-colored ribbon. At the back left is an electric motor that would fit in the case, were there a case.
The number keys are marked: 7 8 9 (/) 4 5 6 (/) 1 2 3 (/) 0.
There is a black plastic cover.
This machine has some similarity to the adding machine sold by Marchant around 1959, in the shape of the keys and placement of the function keys and print mechanism. However, it is considerably wider.
