S is for Still Unknown, but More Clues?

Posted here before, once or twice I think, I won't link back as there's probably more information in this one, unknown spacemen, and they're still unknown, but a few clues and the missing pose, with extra colours, might jog someone's memory?

 

This is the current 'here' sample, actually shot weeks ago and off to storage in a day or two, I think the older post used a different sample, and the two can be brought together (with a third lot?) at some point for a more definitive post, if we get a brand or set-title, at some point!

I shot them all twice as the colours were a bit 'fluid' under different light conditions/flash, but there are two reds, one pinkish/heliotrope, the other more fire-engine! And three distinct greys, one blueish, along with a caramel version of the toffee!

But these came with them, in the same blue as some of the figures, I think Shaun associated the figures with a 'space tank', from hearsay/without pictures, could they be the ones Chris sent which we looked-at here, the grey is similar, underside is similar, but they have revolving turrets? It would certainly allow two 'sides' to have vehicles? There's probably a play-mat and some palm-trees missing! Shades of Y-Wing fighter to one of them?

These are some 'suggested' names I gave them, as they seem to tick the boxes, making them maybe mid/late 1990's and the new Star Wars trilogy pushing Buck Rogers repeats off cable?

While I was PlayPlax'ing the other day!
