I built the Napoleon version of this car quite some years ago, not sure now whether it was a Heller or Italeri or some other manufacturer. Unfortunately, it got damaged beyond reasonable repair over a couple of house moves.
I just finished Revell AG 1945 MG TC. To keep the Revell AG theme going, I dragged the Jag out again. Started building this at least a decade ago, and put it away in frustration. So far I've cleaned up the body, opened the doors on each side, opened the boot (trunk in USA lingo). The doors have prototypically correct hinges made from brass plate. The interior panels also had to be cut once the doors were opened. The opening doors also meant I've had to cut recesses into the chassis or floorboards where it's recessed at the door areas, and build up the panels at the front and back of the door jambs. Consequently, the underside of the doors have been built up to the correct profile. Pictures to follow in a later seperate thread.
