I had a flexowriter that was at least a full generation newer than that one, at least judging by the general styling. It needed a procedure about every week or two to free up a bunch of oval-shaped wheels that touched a spinning drum that looked like a typewriter platen roll. When the oval wheel dug into the spinning roller it flipped the roller over, driving the type bars up to the paper. I think the roller got a glaze and the wheels wouldn't catch or something. otherwise it worked fairly reliably, and had paper tape reader and punch. Jon
