I looked up as much as I could about this show around the internets. Mike Lech was actually a quite accomplished professional model builder. The show was funny because, he had to play dumb and ask silly questions so that the show could explain techniques. he has some classic moments and you can tell he is trying hard to keep a straight face if you watch them on you tube. In fact sometimes he made mistakes on purpose. I owe a lot to Mike Lech, if it wasn't for that show I wouldn't have been building models for the last 25 years.
I was also in the "young Model Builders club" and would get a mail order model every month. Those were the days.
