I had an interesitng conversation about wing beading with MMC, back in 2016 which I can now relate........
The standard wing beading was black plastic. At extra cost you could specify a coloured wrap, which is basically a leather offcut, although it may not always be leather, but that's another story. My red Roadster was ordered by the dealer with red wrapped beading, which is a perfect match. When I compare my red wrap to a red Morgan with standard black beading, I think it looks way better.
When I ordered my Plus 4, I really wanted a yellow wrap, but I was warned by BHM that the factory often used what was to hand and so it might end up on the beige side of yellow, or paler. So......too risky.
I therefore decided to go for a black wrap, because the wrap increases the diameter of the beading, and for me, is a better proportion.
Anyway, the options list specifies a "coloured wrap". MMC then argued that black isn't a colour, so the option is either black plastic unwrapped or "colour" wrapped.
It took a few exchanges before MMC was persuaded that a black wrap was within the scope of a coloured wrap, but I was told at the time not to discuss it further. I got my black wrap, but if that conversation is anything to go by, my Plus 4 is the only Morgan with black wrapped wing beading.
