In order to verify all the translated documentation from Soviet/Russian sources, especially when checking Soviet aces claims, the author would wish to:

• Obtain Luftwaffe losses database in the Eastern Front.

• Obtain Croatian Air Force losses database in the Eastern Front.

• Obtain Finnish Air Force losses database in the Eastern Front.

• Obtain Hungarian Air Force losses database in the Eastern Front.

• Obtain Italian Air Force (Regia Aeronautica) losses database in the Eastern Front.

• Obtain Romanian Air Force losses database in the Eastern Front.

• Obtain Spanish Air Force (Ejército del Aire) losses database in the Eastern Front.

It would be a pleasure to contact Mr. Matti Salonen for Lutfwaffe and Finnish Air Force losses database.

In exchange, the author may exchange his Soviet Air Force losses database in the Eastern Front (in embryonic state, but growing by the day, 3000 German aircraft data and 600 Soviet aircraft data), and his translated files from Russian to English or Spanish language.

A NDA (Non Disclosure Agreement) formular may be signed at any researcher's request.

The authors thank in advance all the received help in order to write their research work as accurate as possible.
