...The "FROG Model Aircraft 1932-1976" book by Richard Lines & Leif Hellström (New Cavendish Books 1989) says NOVO - A British Company - (1976-1981) "acquired" all but the Axis aircraft moulds shipping them off to the Soviet Union where subsequently millions of kits were produced some of which still for sale today.
Even as NOVO was commencing operations several Soviet toy manufacturers most notably Novoexport - a state-owned Enterprise - were producing old FROGs from 1976 till 1989 probably as well up to the dissolution of the Soviet Union on December 26, 1991. The FROG Model Aircraft book (page 196) says they'd produced 2,750,000 as "NOVO" kits though technically they weren't, couple of these I'd came across whilst building in the early 1990s.
Far as I know none of the post WWII FROG plastics are currently in production. The FROG Model Aircraft book said the "Soviet" molds were not well cared for even in the 1980s so guessing going on near 30 years later they've been "recycled", are land fill, or a lucky couple in the hands of an old model mold collector.
