Antenna masts on canopy (or not) were a conversion done in the field, which is why you see so many werk numbers in the same block..some with the antenna...some without (the wire interfered with the opening of the Erla Haube). I beelive in 1945, the standard changed to remove completely...
As far as I know the tall tail wheel was first implimented in the G14...unless stocks arived early for the late G6...?
I would speculate G14 myself...
