Can someone please explain what these three numbers mean on the pedal crank housing? I believe this to be the pedal crank housing from a 1956 Spitfire Ladies Bike.
The Schwinn Serial reads M0D502 (hard to see but top left) The next number reads 46772 (medium right) The large number reads 13 5 124
One of my concerns is this... The Schwinn serial numbers that date the bike to the fall of 1954 or 1956, but I believe the Serial numbers for 54 and the 56 were located on the Left Rear Dropout - not located on the bottom bracket of the pedal crank housing. Why would this be?
Additionally what does the 46772 indicate? and what does the 13 5 124 indicate?
Thank you so much for all of your help!
