Sorry to have to tell you that when I cleared my dads house in 1994, after his death, all the photo albums of the family business had disappeared. You are right - the site is now part of the Collier used car dealership. The address by the way was not Sutton Rd, as most people thought, but 2-4 High St. I never realised before that the shop smelt of pipe smoke, I guess I must have been used to it.
