I'd post photos of it but I can't be stuffed resizing them to under 800 pixels wide. I don't know why JNC reduced the max width to only 800. I can't update any of my other threads now without re-uploading every image at the reduced size! :td:

Sorry about the side track. Keep up the good work Rotorking! :wink:

Cheers,
Danny

How much did they have in common with the piston-powered RWD Luce? We got the LHD Luce/1800 here in the States.
