I don't have the kit - and in fact haven't seen it in person. I did, however, take a look at the Revell Germany website, which has an interesting story to tell. I can't sort it out completely.
To begin with, it's important to bear in mind that there have been two German sail-training ships named Gorch Fock. The first one was built in the thirties, and was a near (but not identical) sister ship of the Horst Wessel, which later, of course, became the U.S. Coast Guard's training ship Eagle. That original Gorch Fock went to the Soviets as war reparations, and the last time I heard was still operating under the name Tovaritsch. The second Gorch Fock is much more recent (dating from the fifties or sixties, I believe). She was built for the West German Navy and, I believe, is still serving as the sail training ship of the new German Navy.
The Revell German catalog lists two Gorch Fock kits: one in 1/253 scale and one in 1/350 scale. I think the 1/350 one is a reboxing of the kit that originated with Imai in the late seventies. Imai did a rather large series of sail training ships, including, if I remember right, both Gorch Focks. They were pretty nice little kits, bearing in mind the limitations of the scale.
The 1/253 kit sounds suspiciously like a reboxing of the old classic Revell U.S.C.G.C. Eagle. (I can't imagine how else a kit would wind up in such a bizarre scale.) If so, it would be quite interesting. As we discussed a while back in this forum (in the thread labeled "Revell Eagle kit," which is now at the bottom of ship forum p. 5), this kit probably represents the Gorch Fock I more accurately than it represents the Eagle. If the Revell Germany folks made a few minimal changes (e.g., the figurehead and the decals), it ought to make a good start for a model. The painting on the website suggests that it has a double spanker gaff, so maybe it did get modified. It probably has some 1950s characteristics, like solid guard rails and those gawdawful plastic-coated "shroud and ratline assemblies," but the old Eagle was basically a nice kit, jam packed with character.
I believe Heller made a Gorch Fock II in 1/150, and it may well have appeared in a Revell box. I think I recall buying it once a long time ago, though I don't think I ever got around to building it. (Quite a few of my unbuilt kits got sold to a local hobby shop when I moved, after I got out of college; I think that may have been one of them.) My recollection is that it was a pretty nice, detailed kit.
All this is pretty confusing, and making my middle-aged head ache. Good luck. Modern sail training ships make nice models.
