Research, got the answer in less than a day.

There are several really good threads on the forum, one had a photo of a 30/98 Vauxhall and I wanted to find another photo of it, to confirm it was the one I thought it was. No luck in some early issues  of the SCCA newsletter, but I found this ad. Went to my copy of the Jack Fox Indy 500 book and the car never qualified in 1931, no photo of it either., but I got the owners name. Bob

I'm in the middle of cleaning out the junk in the office, looks like something on American Pickers. Found some auction catalogs one from Pebble Beach week 2006. Flipped through it and stopped right here. The car was renumbered 24 and ran in the 1934 INDY 500, finished 10th. Hope it is restored, and maybe Vintage Racing today. Bob

Little Google time and it is alive and well Vintage Racing in Montlhery, France. Photo 3 shows the nose of the Schafer 8 Buick that is also in Europe now. Bob

I have some other photos of the Shafer 8 and the Graham 8 (#24) which were sent to me by Thomas Schott.  He and his friend Miro Geiger drove the two cars at the Monthlery Vintage race back about 2012.  Thomas and Miro co-drove the Graham car at Nürburgring for an event.

Thanks Gary, kind of a shock to see the Schafer 8 painted green, it was Maroon since the 1970's. I good friend in Massachusetts campaigned it for years, still holds Pre War VSCCA records. Bob

The Graham is painted Avon Blue the first pearlescent color Graham offered in 1932, at this time it is the only known Graham wearing the color (they found the original color during the restoration).  A friend of mine supplied the Graham block, great to see these cars still on the track.  Amazingly the suspension and drivetrain of the Graham are essentially stock, apparently in 1934 just reducing the weight made a pretty good race car.

Interestingly, a David H. H. Felix from Philadelphia who was a famous labor lawyer and repeat Socialist Party candidate for House and Senate seats in the 1930s. His collection of scientific instruments is part of the foundation of the Smithsonian Museum of Science and Technology. Owner of the car in the book has the same name and hometown.
