List of British frame manufacturers / UK frame builders

Surely Witcomb have to be added?
They're still making great frames though prices recently went slightly up :-/
Quality builds with a rich history which includes Richard Sachs.

I like Witcombs, & think the shop looks quite smart now, but I think the majority of their business is putting track ends on road frames for trade business at the moment.

Interesting to hear them featured on Robert Elms the other week. No prizes for guessing who featured heavily.
