What fantastic news that this bike has gone to a good home and a retrobike member. Doctor Bond i'm sure you'll do the bike, Gouldy and RB proud. I cannot wait to see some proper pictures of this and read the memories that it will undoubtably stir from the retrobike community.
As for what you've paid have no worries it will only increase in value i'm sure. To let you in on a secret I was prepared to pay in excess of £700 for the Timmis Dyna-Tech and would want a lot more than that if I was ever to sell.
All the very best with it.
Mark.
