Hi All: I friend who collects old Schwinns, mainly single-speeds, came across a Regina Futura freewheel set. It's in a nice wooden display box and has one freewheel body and three 6spd. gear combinations to put on it. It has the newer removal system, not the old strippable variety. Can anyone tell me more about these? What should I offer him for it? Thanks, Mark M. Koepke, Stevens point, WI --- USA
