Many years ago, I attempted to figure out the various Watson Roadster chassis and simply missed the mark due to not having the detailed records which now seem to have surfaced, basic ignorance which made me miss some of the more obvious clues, and correctly figuring that someone much smarter than me would eventually wrestle this critter to the ground.
Gary came up with 23 Roadsters that A.J. Watson built, which initially surprised me since I thought there were more -- turns out that I was counting the clones and copies as "Watsons" as well before I figured that one out.
At any rate, I used the system to identify those Roadsters I found based on the one which was moreorless used by the constructors and the Scribes as a relatively painless way of sorting out the various chassis -- the date the chassis was made (56) and then assigned a number in that years build (56/1). I was close to what Gary has in some cases, but completely missed the boat in others.
Here is what I am using based on Gary's wonderful work:

I hope this helps some of you. Needless to say, Gary's book is a great resource and cleared up more than a few mysteries for me.
