Thanks very much Boggie and krow113, your help has been excellent. I have ordered the MFH chain set from BNA model world, it is coming express post so should have it in a day or two, I'm hoping that the 1:12 scale will be okay for my application.
krow113, you have done a superb job with your bikes, especially like the 47'Bobber and its girder forks, my 39' BSA M21 (real one) had girder forks.
