This kit was produced by the Czech company "Igra" some time in the 1970s-80s (not sure exactly when). They produced a number of other kits like this, including a Vasa and Golden Hind, with wood hull parts and moulded plastic fittings, and they also made some kits intended for R/C, with vac-formed plastic hulls. Not sure how many of these there were, I've seen a Soviet Shershen-class torpedo boat and a small fishing trawler/drifter.
I bought the torpedo boata few years ago, but ended up selling it on eBay as it was so crude - basically, other than the deck hull (which wasn't very accurate in shape) and deck, you just got a load of pre-printed sheets of dubious quality plywood and cardboard! Your "Havets Vinthund" looks a bit better than this at least.
Don't know anything about the ship itself, other than that it's a 19th century clipper, but the name is Swedish and means "Sea Greyhound" so presumably the kit is based on a Swedish ship; web searches only turn up links to this kit (on eBay etc.), though.
Having seen this kit myself on eBay numerous times (but put off bidding by lack of knowledge of the kit's quality) I'd be interested to know more about it - would you be willing to post more photos of the wood + plastic parts? It looks to me like the hull is plank-on-bulkhead construction, some other Igra kit's I've seen have had "bread and butter" construction hulls which appeared to be balsa.
