I have european version of Cobra Invader, part of StarBrigade subset (with Payload figure). Mint condition (all parts in sealed, original poly bags) in open box (just to check). Inluding a blueprints, a catalog and a figure: Payload. Box has an unique box art with Payload insted of Astro-Viper.
If someone interested I will exchange that with some vehicles, vehicles and figures or figures (I'm not selling it). Just write what You offer and in what condition... Worth to have this in collection!

It's not Polish.
There are 2 version of that one.
Itlian, Spanish, English variant and
Dutch, French, German variant.

Allthough I know another polish collecter who had bought it there, but I'm pretty sure it is import in poland
