PORSCHE DOG DAYS

It's difficult to comprehend today but back in the late 1960's and into the 70's old/obsolete racing cars were not valued .I recently found these photos in my files.They were taken at Brands Hatch in either 1967 or 68 on an Olympus Pen half frame camera .The Porsche 904 would be worth a fortune today but back at that time it was just another rough club racer.Can anyone throw any light on the identity/history of this particular car ?
