The serial numbers found on the frames of your WASP and your Starlet suggest they were built in either 1952 or 1957. Since there were no WASPS in 1952, that tells us the frame was built in 1957. The 1952 Starlets were still being pinstriped by hand in 1952, but were stencil painted, like yours, in 1957. According to our friend John, whose family owned and operated a Schwinn dealership in the late 1950s, and who sold a very large number of WASP bicycles to local paperboys, the WASP wasn't sold with fenderlights because they got in the way of paperboy baskets. Regarding the 1957 Starlet, and this particular point deserves additional research, we see in the available Schwinn customer handout that the Starlet had transitioned to the middleweight designation, whereas your Starlet is a ballooner (please confirm tire size). If it is true that your bikes were built in 1957, then their distinction as "Lime with Black trim" is in question.I would think they would be from the 1954 model year as your catalog scans suggest. I see there are serials for 1957 for both, just wondering why you think 1957?
If the speculators choose to contribute to this point, it is fair to ask them to document all of their evidence.
