Hi Kevin,
Here's another lead for a Commer Q2 in Belgium. It needs a lot of work but at least the essentials seem to still be there. It has been for sale for quite a while and as far as I can tell was still present in 2021. If you're interested I can send you contact details.
As you can see, this has been fitted with a coach built cab after WW2. Looking closely at the scuttle/ cowl, I noticed the windscreen is part of the coachbuilt cab, and not of the original cab. It seems to have been a flat-face cowl supplied to a coachbuilder. I think this was a Welfare Van originally, as used by the Food Flying Squad. After WW2,
a dozen Commer Welfare Vans were supplied to UNRRA and sent to Belgium. I think this could very well be one of them and it would make one heck of a resto - a very difficult one, but really unique!
