Here's two links for 'ya!
This site has some way-cool shots of a restored '64 Watson Offy and a car from 1947.

This one has a bit of this and that, but they're all photos from a fellas personal collection. Some of the highlights are Jackie Stewart at Indy in '66 (not a roadster, but GREAT color shot thru the fence) and a couple of shots of Jim Hurtubise in the Mallard at Indy in '71. GREAT stuff here...
