As a result of some very sad situations and a combination of "friends" who did not get on too well with Alan Crocker I sadly lost touch with Alan at the Christmas/New Year of 69/70 and had no knowledge ( as an insider) of what he was doing after that. I wish that had never happened, he was a part of a very interesting family. His dad Bob was an amazing source of knowledge too, but that is OT. That, in my mind, dates his Valour (at least the one I had involvement with) very clearly.
Earlier I referred to an FF with "one too many gears". Howard has mentioned that car, being the same one that lost a wheel. The gearbox issue had been rectified by then.
