could any body tell me if keil kraft are still in buisness if so what are the unmade wooden boats worth
I think that Keil Kraft actually made very few boat kits - just their EeZeBilt range and their 'Galleon' range of static galleons (and the Galleons were originally a separate company). However, they were sole distributors for several other kit ranges - Maycraft, Aerokits and MarineCraft, for example. They also did a range of polystyrene boat kits, and sold Bowman yachts for a while...
Keil Kraft, as the site indicates, are now long gone. Amerang hold the rights to the name but are entirely interested in a wide range of model imports and no longer manufacture anything wooden. If Keil Kraft were still in business you would have no trouble finding out what price their kits were!
Unmade Keil Kraft kits go for varying prices, depending on what you have got. If it's the LesRo pilot boat, that will be a fairly recent model - but it's rarer than the common RAF Crash Tender. I guess it should go for over £100, but probably not as much as £200. At the moment there's an Aerokits Patrol Torpedo Boat being sold - a bigger kit of the same vintage, with the accessories but without plans (which, incidentally, are readily available). I would watch that, it will probably go for much the same as the Pilot Boat would:
