Weird War Soviet, a start

[Maichus]

You can get those Karmans cheap as chips (starting at € 5,- for a box of 4) from Ludik's Bazar in France:

Postage to Sweden might be a bummer, though...

I use GW Valhallans as soviets. (umm, I really should finish painting though...) I also got some Chiltern Miniatures russians, that are very similar to the valhallans in poses and style, but bigger and much cruder sculpts. I always planned to paint them with grey skin to represent Ivanov's human-ape hybrids.

Superfigs do some soviet style superheros, including a massive Stalin figure. (somewhere on witchhunter.net there is a picture)

cackling, screaming, ukrainian cannibal ghoul 'partizans' or cannonfodder is a plausible option too.

both Forces of Arms and Warlord Games do some interesting Soviet vehicles that can be used to mount Weird Weapons.

Thanks for the advises, I'll have to look into the Dust Gorillas again and I'll check Ludik's Bazar. Worst case I'll get some from Ebay and ship them to my in-laws in the states.
