A lot of what you have said is right, Bill, but I can't award a point yet.
It's not one of the Martel designs. There are some similarities, but they were the other way round to this, with the tracks at the front, and the steering wheels at the back. Having said that, Major Martel obtained his track mechanisms from the same company that converted this chassis, and whose name you have almost got, but not quite.
Morris is also right, but the name badge would have had a second word on it as well, distinguishing this from Morris's passenger cars.
LOCKED for Bill's next reply, to fill in the details.
