Really nice work - great to see more Stags getting built!
Couple of comments. The Auxiliary fuel tanks were often dumped in the field. They don't appear in too many archive photos. Same goes for the mirrors on the front mudguards i've not often seen them in pics either. As to stowage, the Stag was the vehicle which had more gear piled on every possible surface. It's VERY difficult to over-do it!
There is one area which needs a little bit of attention - the rear exhausts. They got VERY hot in service and any paint would quickly burn off - many stags were also seen with a cover over them and a lot with an extemporized water heater added on as well.
Nice Work!
