In 1981 I was 31 and hadn't built a model for 15 years. I was in the London Toy Museum and in the shop was a copy of Dennis Doty's then new book, The Complete Book Of Model Car Building.
That book, with it's nostalgic look at 60s kits and clear, do-able how-to's was what got me started again. Particularly the section on BMF, which I'd never heard of, intrigued me. Since he provided their address, I ordered a bunch immediately and I've never looked back.
