"In the May 7-9 Laguna Seca Regional race program Don Cummins (no "G") is shown as entered in a No. 45 scarlet and gold BP Jaguar E-Type.  The January 1966 issue of Motor Sports International includes a partial B+W photo of the Cotati 4 Hour enduro winning E-Type driven by Don Cummins and Larry Albedi.  The cockpit close-up shows the same shaped roll bar as is seen on the Jag in the Fuchs photo from Kirker Creek.

I've noticed in your Old Race Car Site photos posted of Ed Leslie's black Cobra "Snake" that it has an off center white number roundel on the hood in the same position as the one in the Cobra trailing Don Cummins' Jag in the Fuchs picture.  Since Foster Alexander had just purchased the Leslie Cobra and retained the black color, the Fuchs picture's Cobra is likely Alexander's."
