"The 410S owner was Bruce Danielson from Redlands California. I believe he was a doctor. He had previously driven a smaller Ferrari.   I believe he called his team B & B Racing. 

Bob Oker drove the 410S for him at a Riverside pro race after Skipper stepped out of the car. Unlike the Edgar 410s this car kept breaking down. This may have discouraged Hudson."

"#246 is Rose's 300S-Chevy raced by Lloyd Ruby.   Re:  the Ferrari in the upper left hand corner, I can find no Ferrari entered with a race number beginning with 2."

(1-11-09)  From author and historian Willem Oosthoek:

"The blue #244 Ebb Rose Maserati in the background was his 300S. chassis 3073. It was raced by Bob Schroeder who retired with gearbox trouble."

(1-11-09)   From author and historian Andreas Dziedzic:

"I agree to Michael T. Lynch that #246 is Rose's 300S with a 5.6 Chevy V8. Lloyd Ruby finished in 5th overall and 1.BM.  #245 is Ebb Rose in his Micro-Lube 450S (4509).  He didn't make it to the grid, because of mechanical woes during the the sprint race on Saturday. There had been a third Maser with a start number beginning with 2. #244 a Micro-Lube 300S with Bob Schroeder, he didn't finish in the Examiner GP on Sunday."

(11-8-09)   More from Andy Dziedzic:

"I hope I found some interesting facts to solve an old problem.  You asked if anybody could identify the red Ferrari in the upper left corner.  Even Michael T. Lynch had no idea.

#212 could be the solution to our problem. This is Loyal Katskee with his 121 LM (also called SuperMonza or type 446) s/n 0532 LM.  He didn't qualify for the main event, because he managed only 46th place (1:29.06) during the practice."

(5-11-10    From Walter Beaumer:

"Willem  is wrong here! (1-11-09 above) The blue/white Maserati on the left is Lloyd Ruby`s 300S, chassis #3052. The car had the rear end of a short-nose version of this type. The later versions of the 300S had a lower rear section."
