This is the Tuna Clipper by Lindberg. It's an excellent kit if you can find it; I believe it has been out of production for a while. I understand this was originally a Pyro kit before being added to the Lindberg line.
I don't recall the scale, but I think it's fairly close to HO; 1/90 or something like that. Except for the rigging and some KrystalKleer for windows, this is a straight out of the box build.
