Not a lot of documentation out there for the Ta-152. I went to the NATS with mine as well and no one knew what it was. I had judges telling me I had wrong colors on my plane and that pissed me off. I even have pics and research from the one at the Smithsonion Cherry Hill facility and this guy is an expert, not. The packet I made for my plane I copyrighted and was planning on selling a docs set. The Scale Masters guys absolutely loved the book I made.
