This is one of the typewriters I bought at Herman’s this year. The 1920s Remington Vertical Adder Model – 21.
I have purchased it from Connor Brumfield. When I bought it the adding function did not work, so I brought it out to the back porch repair session at Herman’s. Where me and a few others tried in vain to get the adding mechanism working to no avail.
When I got back I managed to get it mostly working but the 6 keys still is frozen. It will also have to have the feed rollers redone at some point.
