I'm the Wiz, and nobody beats me!
Yeah I saw that, cheers! It doesn't really help though. It suggests that the serial number I have should be stamped on the rear dropout, which it clearly isn't
Not sure why you say it suggests the number should be on the drop out? That placement occurred on the 1952 models, and prior to that every Schwinn made had the numbers under the crank.
