Dating the post war X serial numbers.
So far nobody has previously answered my question of when the X serial numbers were used. Over the prewar war years the lightweights had the same prefix letter as the balloon models on the one piece crank shells and the serials on the three piece crank shells had the same prefix letter and only 4 numbers that were hand stamped all thru the late 30's and 40's prewar and war time era, and into the first few years of the post war production. I believe it was 1949 when the lightweight three piece crank shells were first machine stamped. This was also the time Schwinn machine stamped many of the Tandem shells with the T00000 numbers that started at #1000. All previous tandem numbers were hand stamped and the very first few produced had just three digits.
Here is a 1949 Continental with a 49-3 SA hub date and a low X serial number. No balloon models had components that were dated other than an occasional rarely seen dated crank to somewhat accurately date those models.
