Thank you Jordan for those posted images. These larger files clearly show the Achilles front aerial base in these instances are the no10 type.
The example of the kinked forward extension on the hull side is interesting, could that of been purposely done by the crew? The bend is too low to have been hit by the rotating of turret/gun barrel. Unless that was weakest point even when the antenna rod was attached which would mean it was smacked from behind?
The close up image with the barrel in contact with the B-Set aerial may explain the added fitting near the top of the mast, specifically put there for when this type of situation occurred? It is that same detail that I had posted as a cropped image with the red arrow pointing to it. Of note too both TD types have images of them traveling with the gun rotated so it is pointed to the rear.
