I've built quite a number of MTK kits over the years and had met Colin more than once. I think, as others have pointed out, that what he did needs to be seen in the context of the time. It's probably no exaggeration to say he singlehandedly kick started "modern image" modelling. His output was prodigious and whilst no-one has ever claimed his kits were perfect in terms of RTR standard of the time, usable. His cast W/M Class 74 needed two Hornby Class 25 m/bogies but would pull anything and was 40 years ahead of any likely RTR version.
Yes, the kits needed work and in those preWWW days if you needed advice you asked around or figured it out for ourselves, it was called modelling. The end result ?
