Most of the infos are just about 190's CoG right?
For the German data:
I have all the load datum sheets on the entire Focke Wulf line from FW-190V5g to Ta-152H1, C, and all the types inbetween. Reports on all the engine changes, production information engines/airframes, flight testing, engine/prop manuals, Fluzeug-Handbuchs for the entire series, motor endurance testing, fuel changes, mixture regulations, anti-knock injection testing for all the systems, installation instructions for Alkohol-Einspritzung, GM-1, C3-Einspritzung, Erhörte Notleistung für Jager, the Beanstandungen's from 1942 til the end of the war, Engineering meetings with BMW, experience reports from Focke Wulf/Geschwaders......
and it goes on. I have amassed so many reports now that I forget them. Everytime I dig through my filing cabinet I find reports that I did not know existed!
I emptied Wright Patterson's archives on the FW190 too. If you go to our Museum, about 75 pages of original Focke Wulf documentation with stamps and signatures is on display that is part of my collection. I have about 50 more pages to add to it at the house. Neat stuff, Kurt Tank was a scribbler. Some of them have penciled in changes while others are covered in notes in the margin. One of the other neat documents in our collection is a handwritten BMW801 TS manual. It's a crewchiefs notes. Classes were given at the Geschwaders in the last year of the war. I have a published copy too but those are very rare. We just acquired an original Ta-152H Flugzeug Handbuch too. Very rare an not cheap either!
All the best,
Crumpp
