The Walther WSR-160 is a pinwheel calculator made from 1956 until 1968. Mine is probably from 1967 or 1968. It has a back transfer mechanism, and all its controls are on the right hand side so that it can be operated with only one hand. I forgot to point out in the video that the input pins don't move when you turn the crank.
I also have a video about a much older Walther machine, the Walther RMKZ:
