How I got on this topic, I don't know, but as a kid we used to play with these HO scale Airfix men, and looking it up on the net I found this site which lists all of the collector's sets available. Looking through these pics brought back a lot of memories. My best friend Eric had a lot of these sets, including Tarzan, the Sahara Fort/Foreign Legion, Astronauts, Cowboys, and many of the WWII sets. These go down as some of those toys that just vanished over the years. Too bad modern kids can't get stuff like this that required them to use their imaginations in their play. Many hours of my childhood were spent with these little plastic figures.
