[QUOTE="Tom Gaynor, post: 14796, member: 4034"] [b]Come again?[/b] I recognise that Birmabright is sh-t metal, but why not just say "sheet metal"? I won't be offended. I doubt anyone else will be. Birmabright is a tradename for a particular manufacturer's version of an ally alloy sheet which contains magnesium: about 7% I think. They make Landrovers from it. That, and ferrous oxide. But the point I was making is that the steel mudguards I have, fitted by the Vincent factory to my Vincent when it left the Vincent factory, in Stevenage, referred to by me as "steel Birmabrights" because they have the same section as the ally version, are much better made than the ally Birmabright mudguards, taken from (the previous owner, a friend, told me) another Vincent twin, also made in the Vincent factory, still in Stevenage, and with which the previous owner replaced the steel ones. Both sets were fitted by the Vincent factory, to Vincents, in Stevenage.

Now that, to me, is very interesting. Maybe I need to get out more. But (not even) the machine registrar knew they even existed. He knew about steel touring guards, with valances, but not that steel "sports" guards were ever fitted. So are my ally Birmabrights, without such a flat, not Vincent at all? An aftermarket bodge?
