Susan, you're in the land of loop frames.Take your pick of any 30's/40/s/50's frames that fits you and go at it. Remember that Raleighs have proprietary threading of some parts so other marques may be easier to deal with. Premium models include Sunbeam, Humber, Rudge, Hercules and Raleigh of course. Good hunting. We think this examplewas a rebranded Hercules.
