Hello!
Several designers have begun BoB-quality-level 3D models a long time ago, and some are known on the sukhoi.ru forum (probably the most important one in Russia; it suffered from a long interruption in 2008 for technical reasons; in a way this is the "SimHQ" of Russia), notably PSY06.
The latter one is known (since three years, that was no secret! no need to read russian...) for a Pe-8, a (gorgeous beauty of a) CANT 1007, an Emily, a B6N (I believe) and so on, plus some boats and ships...
Go there:
http://www.sukhoi.ru/forum/misc.php?...ments&t=44889; you will see many images of private projects as well as some Galba stuff from SaQSoN (beware, this is the list of the attachments of this 1200+_messages sub-forum, there are many images, not all of them boB related, of course!).
Alex Voicu who is the creator of the Il2 Tempest has also begun a while ago a gorgeous Typhoon meant to be integrated in SoW series (see SimHQ for this one)
FooBar is a rail road specialist and has many images on his site on Ubi.de and also on SimHQ.
Obviously many of these works are on hold, because you can do so much (not a lot more than the basic 3D model, unless you are privy of insider knowledge!) until you have the SoW SDK which will define the way the "special" 3D parts, LoD, internals, DM, various tricks, maybe FM, and which texture sizes, numbers and nature can be used.
