I wish I knew more about this photo -- but the caption is all the information I have on this little racer.
OCELOT -- That's the name of thie weird job that Bill Krause drove in exhibition lap at CSCC Riverside races. The tiny kart-like job weighs only 250 pounds and is said to have maximum speed of 80 mph. (MOTORACING photo by Bill Norcross.)
But it is certainly a change of pace for Bill Krause to be driving a little car like this one. His usual rides were more like the Maserati pictured below. (Laguna Seca in 1960)
