I have on eBay a 1960s SCM (Smith Corona) 250 Electric Typewriter. It has a few faults: 1. The carriage does not space after the keys are pressed. 2. Some keys get stuck. 3. The top ribbon cover has came detached and the screws for it are included and a key may get caught against this. But, it is in very good cosmetic condition and it includes the original manual and still good quality ribbon. The listing is here:eBay listing
