That is a beautiful bike and it should bring at least the $800 ( I think maybe more) that was mentioned. When you do present it for sale , I would look for some short valve stem tubes(available on eBay) and, as SurferRosa said , center labels to coincide with valves. Also lower the seat post to relative position for “right sized” rider. Shorten the brake cables a bit as well, running them in front or behind is a personal preference but most like them behind the bars. This may seem overly picky but this bike will attract the kind of buyer that would notice. Whatever you do , good luck and too bad it doesn’t fit , it would be hard to replace in that condition.
