There are several surviving Fw190F aircraft, perhaps you can contact one of the museums or private owners?
They are:
Flugplatz Museum, Cottbus, Germany
Aeronautical Museum, Belgrad, Serbia
Smithsonian NASM
RAF Museum, Hendon, England
Collings Foundation
Another source would be Flug+Werk (Germany), who manufactures modern reproductions of the Fw190 (Fw190A), and may be able to provide very detailed information.
