I don't understand how the Staples advance forward it seems to maneuver up and down as it should. I got one staple to advance and then run through and work as it's supposed to but I don't get what pushes the Staples forward so may need some work or maybe is missing something I really don't know much about these very cool early stapler please see photos any questions please ask may may need some work or maybe missing something don't really know anything about this but neat piece
