Hello Jon
I knew Oliver, raced at CRYC and up until a couple of weeks back owned two of his mid 80's marbleheads, I spent hours with him in his workshop in Burnham on Crouch while my boats were being born, if you would like photos of the boats, let me have your email and I'll bang a few off to you, do you know, I don't recall them ever have a "type/model" name just simply oliver lee marblehead, he was way ahead of his time then and everybody knew him, he produced the F1 of the model yacht world in my opinion.
It was whilst doing some of my own enquiring research into Oliver that I came accross your interest. I was looking for something that he, Oliver, once designed and produced in small numbers................a fascinating mini half tonner or one tonner, may even have been a Dragon I think, I can't remember, also can't recall if it was keel or centreplate but, the helm would lie down in the hull and operate the rudder with their feet whilst operating the sheets in the same way as a full size boat...........brilliant and I want one if anybody has any idea of one available.
Anyway, let me know if you want some Pics
Chris
