That is good news Graham.
I would strongly disagree if that means the drawings, as a piece of HRD history and useful technical information, are lost from view to the world's Vincent Owners.
For my part I have a pair of as-cast cam-boxes and would dearly love to see the drawings so that I can machine them properly for my own A project.
Is this the thin end of the wedge? Are we to assume all Bob Stafford's 'A' drawings and sketches are going to be removed from him and put in the secret vault too?
You're more than welcome to see the drawing - I've not reason to see why it should be a secret!
is there anyone who would like to see it published here on the forum?
