Schwinn Sales West
I live for the CABE
To confuse the view further, The Pop Brennen built bikes used the double wrap around head lugs also. Some vendor made those lugs, and it likely was not Wastyn/Schwinn, or Brennen.Fabulous original provenance letters.
Thanks, for sharing those.
They are Wastyn built, as we’re all the Paramounts up until the late 1950’s.
Since Schwinn and Wastyn had a well established working relationship, and Schwinn had the state of the art painting facility.
Most if not all of the frames that Wastyn built, were painted at the Schwinn facility.
1937 jives on the all white tall frame bike, with the other two “Window” type headtube lug frames that are in the registry.
All of the early frames were built to order, so, I guess you could say, that up until Schwinn announced their official Paramount/Superior lightweight line in 1938, they all could be considered prototypes.
Note this image from the 1938 introductory catalog, showing the “Window” type headtube lugs.

Shown here on the Sports Tourist model.
I have not actually seen an early Sports Tourist with these type head tube lugs, but we now know, that Wastyn was using them early on. (Pre 1938)
So, I wouldn’t doubt that a early Sports Tourist frame shows up one day, with “Window” cut out head tube lugs.
The other two bikes, smaller mens with red head, and ladies model, are definitely postwar era bikes.
Most likely 1948ish give or take.
Just a guess
