Hi Woodsy
I know this subject is popular on Moonbase.
Here's part of my space hard plastic collection comprising Tudor Rose, Kleeware, Pyro and other manufacturers. I was lucky enough to meet Lester Harrison back in the day and he was generous with his information.
For the sharp eyed there are a few undocumented pieces sitting there.
I'm always keen to trade. My current passion is Dan Dare.
