Paul,
I do have some pics of the TR6 and the BGT, I will transfer them off my camera's memory card and post them up here shortly. I wish I had some better digi pics of the TR4 but when I took the one I put on the board here it was -20 degrees outside and the car wasn't about to venture into that arctic blast
I always liked that TR4s had a hole in the front grille and radiator through which you could insert a crank handle if the starter lunched itself! Only problem was that my '4 had a "fast road" built engine in it and it would be hell to kick that high compression engine over on a cold morning!
By the way, I did have electrical problems with the TR4, voltage stabilizer blew and I was greeted with a cloud of smoke one day while driving.
