Last I heard there are over 2200 member of the VOC, there are quite a number of owners who are members of local section of the club only, not the 'parent' club, shame on them. This is and always has caused heated debate.
Thanks for all the feedback. That has satisfied my curiosity. I was only after an aproximate figure for club membership being a new member myself.
I do have another question which will help me put this figure into context.
Of all the Vincents originally manufactured is there an authoritative estimate as to how many remain or are at least know about?
