This was my first bike, has to be a 40's or 50's, I made a sting ray out of it when sting rays first came out... yea, that long ago. It is a 20'', had a coaster brake, had forks with hollow blades, it has no serial #'s... I guess never. Thought it might be able to be identified by the seat stays/chain stays, also the crank. which has a hole in it, no threads, instead of the usual pin coming out of the arm, to catch the sprocket. The chain guard looks kinda universal, but was on it when I was riding it way back when, with training wheels. The crank reads HO 5 CO on one side, (the "5" is probably arm length), and the other side has two backwards (1's and then a "y"), (or would it be Y11?), and a round insignia, with something inside it I can't make out. Would very much appreciate any info as to what manufacturer this bike might have been.
