I wasn't aware that Schwinn still made a bike with skiptooth drivechain in 1964. :?
Go to Old Roads classic and antique bicycles and look up "Schwinn serial numbers".
Looked to me to be early 50's. K456312 is too many numbers to be a 64'.
Oh would you look at that! I overlooked that detail. It looks like a middleweight frame though and has the serial on the dropout. Early 50s had 5 digits after the letter and 60s is 6 digits after a letter.
It almost looks like somebody had a ballooner with a frame or paint in poor condition and transferred some ballooner parts onto a newer frame? Possibly? Schwinn used drop centers before '48 so those could even be from a donor bike as well. It could have been done a long time ago too as piecing a bike together is not a new thing, I wouldn't imagine. That's as good a guess as I have! Any thoughts?
