I've never seen the kit and I'm not familiar with the manufacturer. I have seen the ship a couple of times. She's a magnificent, imposing vessel and would make a beautiful model - though at that size the scale must be awfully small.
Back in the late seventies and early eighties Heller produced three latter-day sailing ships on 1/150 scale: the 4-masted barques Pamir and Passat (virtually identical kits, I think; the real vessels were in fact sister ships) and the 5-masted full-rigged ship Preussen (different major components, though some of the fittings from the other two kits may have been recycled). Heller kits have been known to show up in Russian boxes; it's possible that this is a reboxing of the Pamir/Passat. If so, it's a pretty nice kit - with a few small caveats. Those latter-day steel sailing ships present some big problems for plastic kit manufacturers. Some of their most characteristic and important features were the mechanical deck furniture - Jarvis brace winches, halyard winches, donkey engines, and so forth. That sort of machinery is extremely hard to reproduce in styrene on such a small scale. The rigging also is problematic; there's an enormous amount of it in such a ship, and such things as blocks and rigging screws (no deadeyes on a ship like this, fortunately) have to be downright tiny. But Heller did about as good a job as could reasonably be expected, given the limitations of injection-molding and mass production.
I believe the Kruzenshtern (sp.???) was built in Germany before WWII - like the Pamir and Passat. How similar she actually is to those vessels I'd have to do some digging to find out. (Maybe one of our European members knows off the top of his head.) If you can post pictures - preferably including some shots of the kit parts - maybe I or some other Forum member can help identify the kit. At least one Forum member is working on a Heller Pamir.
Sounds like an interesting project. Good luck.
