VICKERS MK6B's resto

[Lynn Eades]

I assume these are two shots are of two different tanks. I can't pick up on any camo paint on the left one.

Chris S., I have the full mount for the early U.C. with the brass gear type base pulled down into place by the big spring. This has a 7/8" bore and so receives directly the "D" set aerial section.
I also have two other bases. One is brown rubber which Im guessing is the ground mount (and should have a ground spike bonded into it?) It has the same sized 7/8" bore.
Lastly, I have another in fibre. This has obviously fitted into a receiver of some sort with 3 screw holes around the bottom at 120 degrees, and a stepped smaller dia. at the very bottom. This one has a smaller 5/8" receiver hole for the aerial mast. I assume this takes an adapter for an even smaller dia. aerial?
Can you educate me on the latter two please? I don't think any of them are the exact same as the one shown on the VLT above. There is one on the VLT at the tank museum (Bovington)
