1947 ? Schwinn Survivor

Nice one ... looks like J71884 = Built 04/24 to 04/23 of 1953
Definitely not a '53.. the serial # is on the bottom bracket. The serial #'s were placed on the left rear dropout starting in '52.

Humm ... I don't find any J numbers on the 48 - 52 bottom bracket chart

J was a pre-48 SN.

Some truth to this.

What I have gathered doing research and asking experts is that the I J and K serials would have been left over prewar BB shells and or frames that had already been stamped prior. A being the first true postwar serial. Hope this helps. Pm me if you have any further questions or would like to add something to the list. Thank you
