Tom, are those your sculpts in the first post? They look really fine.
Here's a link to the wikipedia page on Buck:
http://en.wikipedia.org/wiki/Buck_Rogers(there's a section on toys, mostly ray guns). It looks like whoever holds the copyright isn't making much use of it. Frankly, I think it's a remote chance you'd be in trouble for making figures for a charity raffle. If you just change the name slightly, maybe? The Spanish figure kit company Andrea does copies of Norman Rockwell and famous pin-up paintings in 3D, and figures based on popular movies, without licensing- the Rockwell series is called Wonderful World, the movie characters have generic names, but are miniature portraits of the actors. You could call B R figures "1930s Science Fiction Comic Hero"....
Tim Richards was the last British guy to do 'rudie nudie' miniatures in a really big way; now he just does 'em on canvas. Several European kit companies have lines of fairly coy pin-up type figures; popular in Europe, frowned upon in English-speaking countries, for some reason. But that's a discussion we won't get started on this forum:wink2:.
