I would be interested in learning more about these. ToySoldierHQ.com describes them as "Space Minis" offered from comic book ads (very bottom of their page linked above). These three pieces are all hard clinky plastic and I am fairly certain everything shown here is from the 1950s.
Space Coupe
This one missing a "wheel" though it's just one molded bit of bling, no moving parts.
Comparison with full size Archer spaceman in the same pose. One excuse for having a weakness for these guys is using them to force perspective in diorama pix, instantly making the smaller one seem further away. Though I'll also admit to thinking they're just totally cool and collect as a completist. All variants on the favored forms end up on the list of things to score.
The figures at either end are soft plastic. I am aware that H.G. Toys also replicated this form for use in their late 1970s flying saucer playsets but am fairly certain these are soft plastic variants on the figure at center, all manufactured prior to 1960. Would enjoy learning more if anyone can shed further light.
These figures came with two small Flash Gordon type ships which are also shown in ToySoldierHQ's graphic of the complete toy line.
With other reduced size Archer & Premier style figures by Tudor Rose.
