Real quick here. I have not built, or do I own, that model. But, it hails from the last good run of sailing ship models sold in plastic. Heller put out quite a few sailing ship models, some better than others. IMO none are to be sneezed at, however there were some skunks in the road, but in every case it's the master modelers who didn't like them.
That being said, no Heller ship model I've ever tackled was less than intermediate-advanced. To me that means a good basic knowledge of how to replace any parts that don't work, and to do enough basic research to correct major flaws, of which there are few. Also, the masts and yards are pretty delicate.
Read up if you will, there's a whirlwind of ship models based on those German ships that became Eagles, Nunes, Focks, and so forth.
The more advanced ship modelers can parse the differences and the inaccuracies, but they all are good models, if not accurate.
My only major gripe in all of this was the See Adler. Von Luckner was a hero of my childhood, on account of a copy of his bio that I found in Dad's bookshelf. Someday....
