TieDye,
I am aware of the information above regarding when CWC started producing bicycles, how many were produced that year Etc, Etc, Etc. However, you are totally confusing two different models and some of the information you posted above is incorrect.
Lets start from the beginning.
The small paisley chain ring was the first style used from the beginning of production through 1936. In 1937 the larger paisley chain ring was introduced. Also, all the 1936 model bicycles used triple step rims.
The bike posted above by szathmarig is a hang tank frame and I am assuming it is the same bike that you now own and posted a picture of the serial number?????
The serial number that you posted is a "D" which based on the CWC dating chart is a 1938-39.
The bike on post one is not a roadster style frame, plain and simple.
And for your information, some roadsters did come with rear racks as early as 1936 (see model 0526)
We are talking pre war CWC bicycles here and not post war since your mentioning your 52 and 53. Those bikes are not part of this discussion but rather the bicycle that is on post one.
Regarding the catalog pictures you posted above as comparison reference. With exception of models 126, 226, and 726, the rest of the bikes are "Roadster" bicycles. The bike in post one IS NOT A ROADSTER. Apples and oranges.
As far as the serial numbers on my blue/red hang tank and my former cream/blue, your are wrong again. D20005 and D15615, both built earlier then yours. Check Mate.....
Post a picture of your entire bicycle with serial D34479
