Hiya …nice photo’s there anorak…its a long time since i saw a cab like that,
You can see how we modified the roof section, that was hand done at first
then motorpanels did them when the cab shell was assembled at coventry,
at jennings we still made all the interior steel work like the floor bonnets and
bunk area, I would have liked to seen the cab with no internals just for old time
sake.

Like these, John?^^^ 
Some of the later photos in the group show the sleeper area:

It looks like this restorer has made the difficult compound-curved corner bits out of two or three smaller panels, then ■■■■-welded them together with a full seam, using a standard garage MIG: a very time-consuming and skilled job. Presumably, Jennings got these bits by simply cutting them out of a new Motor Panels roof.
How many cabs did Jennings make, before Motor Panels took over? Did MP do it the same way, or did they modify the press tools to make the individual panels without having to chop up already-made rooves etc?
