My nextdoor friend has one of these in mint condition, not used since the early 70's. Looks like a fun machine. But I have no idea how to work it. I think the wringer era is dead with the abaccus.
The wringer era is still alive at my house. I have a '53 Kenmore wringer and a '67 Kenmore Visimatic wringer. Both are used weekly with excellent results.
