Has anyone got a drawing of Vincent Mk 1 and 2 camshaft .I have seen drawings of what they do but not what they look like.

I certainly have not. It might exist as a drawing of the master. The drawing of the masters might be useful, but it would be well guarded I suspect. When I had a cam made for the racer I had to pay $700 for the master. It is a one time fee, but the cam maker cannot tell you what the cam specs are because all of their equipment is direct read for solid lifters. You have to put a Vincent cam in an engine to get the correct timings because you have to use the Vincent geometry of the cam followers, push rod placement and rocker arm and valve placement to get an accurate timing reading. Having to do this makes the cam itself somewhat inscrutable.

Will you settle for photo's?
I must have around 5 cam assemblies and they are all different.What I want is a drawing of an original.
Considering they made only three post war cam designs, that is a problem. The most I can tell you is to try them in an engine. It is not a good answer for you, but if you had the chance to compare your cams to all three drawings and two or three were not identifiable profiles you would have to install them in an engine to see if they were useable.
If someone in the UK has a cam machine you could try that route. I made a cam machine to test cams so that I did not have to put them in an engine. The machine has to match the Vincent geometry and use good parts.
It only takes a few minutes to find out the timing of the cam, where equal lift is located, the maximum lifts and the unfortunate dips. I have run about three dozen cams through it over the years and I have quite a few to go.

original mk 2 should have a 2 stamped on the side of the lobe. mk 3 has 3 stamped. Vincent cams , I read somewhere , are not known for their accuracy. How about put them all next to eachother, lobes pointing upwards, photograph and post the results so we can see them.
Please....I don't understand..what is SPACE in a garage???????
