I found this web site on another forum and found it to be very interesting (even if I don't read, write or speak Russian) and figured that some of you might be interested:
Http://www.wunderwaffe.narod.ru
The site is very heavy with ship and aircraft subjects. When you pick a subject, it will bring up a list of items. From what I can determine, the last two items are drawings and photos. Give it a try.
