Hi Mike, I have the 1944 Field Specs No. 1023 for the 6 Seater which I kindly got from Keith, as well as most of the photos I use as reference in the rebuild, cheers Keith.
The specs lists the usual spares that go in most vehicles, accessories,tools, ropes etc. I have a lot of the required parts plus a few map cases and DD luggage and other officer garnish. Still looking for a folding table, a single scotch and bits I didn't know I needed til I see them.
There are clues to be found like lights, dome (2),blinds, poles extension and others that had me head scratching until it dawned on me what went where.
The gun mounting pictured is listed as "Mountings Bren Gun Roof (4)"
