The James B2 has come together as a result of a James Engine and gearbox I bought off of ebay. As it turns out; the James engine and gear box were from a B2 motorcycle, which is evidently a rare model. As a result of that information I have been able to find a James frame for that year, front end, another gearbox, and a few other parts. Funny enough my luckiest find was when I bought a Matchless CS to find it had the rare James front wheel on it.
