Thanks for the welcome and for the tips. Glen, yeah AccessNorton has a ton of good people and unfortunately a few like Beng. he actually PM'd me trying to get my goat some more.....i just ignored him. These pics are actually in the living room of the current owner. He has owned it for 13 years and has never even ridden it. Shorty after purchasing he became legally blind in one eye and doesnt feel comfortable riding anymore. It's currently at a shop i trust being gone over and checked out so it'll be ready for sale. When it gets to my house it'll join my '68 Norton Commando Fastback, 73 Norton Commando mild custom, '74 Honda CB750 cafe racer i built, and my first bike: '82 Honda XR80 that i got when i was 10. (currently 31, i'm betting that makes me pretty young for a Vincent owner) It would be tempting to keep it in the living room, but i'm sure my kids would climb all over it.
While i'm thinking about it...i see what looks like a breather on the front cylinder intake rocker cap....i was reading somewhere that this was a series D thing that some people retrofit. Does that sound right?
