Thanks Guys for the advise so far its much apreciated,
I will get some pictures up soon, just very time poor at the moment.
My car has a single piece rear window and no TJR stamped in the fire wall, I had assummed that after WWII that most of the car may have come over as a kit, as I believe we had steel shortages around that time,and only assembled here with some local content like quarter windows. From what I have determined the door latches are different to the US models as well. Anyway thats all speculation and the origins of the post war models and details would be quite interesting to find out. Mines pretty much stock including the valve radio.
