I'm wanting to make my HL Tiger 1 into Mid Prod Befehlswagen of the 507th commanded by Major Schmidt. Looking at some ref pics of the exhaust plate in the rear, it displays an Antenna storage metal tube. Some have it mounted either left or right of one of the exhaust stacks. The references I have do not display in clear detail:
A.) The type and/or shape of the bracket. Was it flat iron welded to the tube or curved?
and
B.) The type of cap / lid, was it hinged w/ a locking clip or possibly a sleeved cap that slid over the opening?
In regards to the antenna, the star portion, was it collaspable? I would suspect so.

Finally, on the starboard side of the hull, I seen mounting posts welded to the armor plating. Does anyone have some close-ups and an explaination on their purpose.
Thanks guys, I know its a tall order but any help would be appreciated.
