That is Ed Debrecht as you can see by the title at the bottom.
I believe that is Jack E. Nischwitz’s Alpine which should be a green SI. According to Jack he ran one of the Sports Car Forum engines in it at one point of the car’s racing career (possibly out of the SCF Series I… not sure but he knew Ron Morris who had the SCF Series I)
Unfortunately, Jack T-boned one of the Group 44 Tr-3s and that was the end of the Series I’s racing.
Ed’s dealership also ran a Tiger too. Bob Spooner was the driver. (Spooner also raced one of those crazy Supercharged Bocar Stilletos in the late 50’s early 60’s.)
