So after a week or so, got the cabinet door back from the 'panel guy' who flattened and rewelded the door.
It is worth noting that there is a tendency for metal to re-warp during the welding of the webbing to the skin which is what happened here, so be warned.
After some spray putty, the door has been sanded flat, primed and painted.
Assembly as per the following images. This process has been by far the most work, i concur with Ninos comments that the coin door is the hardest part of a restoration, but definitely worth the work.
Only thing left from here is to have the front metal shroud and coin return flap re-chromed and stick it all back into the caninet.
Enjoy
