I'm looking for some information on TR7 handbooks, mostly related to P, T, and S registered Speke built TR7s.
What I'd like to know is when the picture of the sunroof handle changed from a straight bar to a round loop one, when they changed from pictures of cord seat covers to ones of tartan/plaid seats, when they started to show the lights in the doors, etc., and when they changed from the A5 portrait format to the larger landscape one.
I have a handbook (RTC 9210 Edition 6, copyright 1976) that appears to be for a late 1977 y.m. - it shows tartan seat covers and a round loop sunroof handle, but a map light at the back of the cabin and interior light in the roof lining. I believe the cars of the early 77 and 76 year models had the cord seats and the straight bar sunroof handle, but I don't know what their handbooks showed. I also think that change from early to late 77 y.m. was about January 1977, and I know the change to 78 y.m. was at the end of June to the start of July 1977 - the earliest 78 y.m. car I've ever seen, a couple of hundred into the chassis number sequence, was registered in July 1977 on a T plate.
