I think they may have been pulling your leg a bit Stewart, I often get this sort of thing at classic car shows that go to throughout the year, along with the wooden chassis.
I know a few Morgan owners who have jokingly come up and asked "did you build it yourself" as a tease, and i did it to a Morgan owner a week last Sunday before introducing myself but with others it is a genuine and strong misconception
I know the wooden chassis was deliberately perpetuated by Clarkson trying to be funny in that 90's programme 'Britain's and their cars' and I can understand the confusion with the wooden frame and the early Marcos but the kit car myth or the idea that some could build their own Morgan from a kit seems pretty ingrained
