John Rowney has been assisting me on the sidelines regarding WXA99. In the midst of his helpful information, he mentioned "A" series, "B" series and "C" series Wraiths.
For the good of the community, I thought I would pose the question here...what differentiates these series?
The internet tells me that some chassis were actually completed during the war, and the last of the chassis were completed post war. Maybe that's a clue?
I understand that my WXA99 was near the end of Series A.

Jack, For all prewar RR/B cars, the company did define series. As for Wraith following series have been defined: A (100 cars), B (200 cars), C (184 cars) and D (zero cars). The C-series was intended to count 300 chassis, but the war started. Yes, a very few cars have been completed (and/or only bodied!) after the war. Chassis number 13 was never used, so WXA99 is the 98th car produced in A-series. Cheers!
Generally speaking, it seems that "Series" is actually a configuration definition. Indeed, it is true that most implemented updates coincide with the arrival of a new Serie. Eg: B-series onwards an updated dynamo with regulator was used. C-series onwards another distributor and oil filter was used, etc...
However, RR did not respect very well this rule: some modifications have been implemented at other moments, right during the production of a defined Serie.
Jack, I do recommend reading following book:

Tom Clarke is one of the very best (if not The Best) author for RR-books.
In this book you will find a list of the most important changes made to Wraith chassis (pages 163-164). Beware: if Tom would have listed just ALL changes, he would have needed to add another volume.
Interestingly, with production-cars that do change continuously, the following can be read between the lines: Interchangeability of parts may cause issues. When your chassis left factory, it was a well balanced whole. Returning to that very first condition is the most easy way to achieve success.
Best regards, Koen,
