Just to put my two penn'orth in
In my dim distant past (probably the dimmer the better) there was a ex-Army Humber Staff Car used as a tow vehicle at the garage where I started my apprenticeship.
Looking at the photo's posted on the seller's ad, I don't remember:-
A bench seat for the front passenger
A glove box
A high roof as shown
A windscreen that shape
A dash/instrument panel different to that shown
What I do seem to remember is a solid lump of machinery that could be a pig to start, and drive, at times (although I was too young I did try) and a data plate, in brass, which
I think was where the glove box is shown.
As a matter of interest, was there not more wooden bits on the exterior
