Back in the 1966-67 time frame there were a couple of injection molded kits produced in Poland by a company called Plastik (not to be confused with the later kits from ZTS Plastyk, etc.). They were 1/75 scale and came bagged.
They were the SZD.18 Jaskolka and the SZD.19 Zefir II.
Has anyone ever seen either of these kits? Better yet a photo of them. Even better yet, does anyone have one or both to sell or trade?
