Hi Bill;
I would agree that the photo(s) were taken at 2 Tk Tps Wksp (Morstel). One thing that identifies it as a workshop area is the sign 'R & I OFFICE, ALL VEHICLES', ie:
The Receipt & Issue office is usually the first place you go when either dropping something off or picking something up from a workshop, or in this case, the R & I office is for just vehicles ("A" and "B").
Also, Maj. Bingham went to the workshop on 27 Oct 44 (see attached diary entry).
Cheers
