I've tried to give a representative example of each model as they would have been back in the day---for example, I tried not to use a photo of a WDF3 with a WDF4 nose & WDF2 side pods! Be sure to click on the links to each model's specsheet for more details.
Mike Henry's WDF1-16 #20 (now owned by Bob Darcey) next to Renny Watt's WDF1
Chris Ronson's WDF2-4
Formula B/Formula Atlantic Cars
Bob Winkelmann in his WDB1 at Sears Point
Darrell LeBlanc WDB2-8 "long nose"
WDB2-4 with the short nose
Unkown WDB2 with the "Sharknose". Can anybody identify the owner or chassis?
