This setting machine appears to work as it should. I have four videos posted of its operation on my channel the link to the first one is below when it’s printing higher numbers, it seems to stick a little bit. Please see the part four video on my channel not paper tested I don’t have ribbon for it, I don’t know enough about it to know if they’re supposed to be any carriage movement or it’s fixed printing in the one area everything appears to add correctly and resets as it should none of the keys stick missing two buttons on the left side for unknown operations feel free to ask questions if you have any, please see photos for dimensions and condition details
