Serial number puts at 1/20/1951.
Nope, prewar! Look at rear fork ends! Most definitely not a’51!!!

All I'm saying is prewar has 5 numbers not 6 In 1948 they started with 6 numbers.

It's possible there's a 6th digit but not part of serial sequence, maybe a stray off to side, separated from the 5 or turned sideways.
I have a 36 schwinn. 4 digits and a disconnected stray digit turned 90deg from sequence

All I'm saying is look at the dropouts--this is prewar and serial puts it at '41.
