The Victor 16-83-54 Adding Machine was made from 1960 till about 1967. It is very similar to the series 6, with a full keyboard, except that some of the controls have moved and are now buttons on the keyboard. This version has an electric motor. I forgot to show subtraction in this video, but that is the same as addition except that you press the minus button.
Here is a previous video about the Victor series 6 and 7 adding machines:
