That chart above, has the dates of C series and if the D series was started on the date it says the next series placement would be that D series Started August 1947.I think I've posted this earlier but Phil is very knowledgeable on CWC dating.....
The key to dating your bike is the Cw symbol stamped after the end of the serial number. CWC ran through the same serial numbers several times from 1935 through 1956 and for postwar bikes the key to dating them is to first recognize the features that define them as postwar frames and then look for the symbol that follows the serial number. Bikes with the Cw stamp were from the second postwar run through the alphabet and the first bikes in this series rarely have the Cw stamp. By the time “D” was reached the suffix stamp became quite commonplace, probably to begin separating the series from the first wartime or postwar “D” serialed bikes. My best data-modeled estimate is that the Cw series was produced from 1947 through 1949. The exact transition from the first series to the second series is still debatable so I have slid the scale a bit several times to try to align it with actual bikes, ads, and other factors to come up with the most likely scenario. The second postwar serial number series bikes were produced with serial numbers ranging from A00001 through J99999, assumedly in sequence. A bike with a “D” serial number would, following this logic, have a build date in approximately mid 1948.

That line goes on too. Saying the run ended in September. Yet it is followed with the year 1952. The periods of the other, prior runs are about the same length. I think it possible September is the line you're looking for; 'The transition from the first series to the second'.
[edit] No, not Sept. exactly, the transition in the D Series would be during Aug. through Sept. 1947. chop that in half, then, September is your sugar daddy.
