Handbooks of Russian aircraft cannons wanted

Hello,

I am looking for handbooks and manuals of Russian aircraft cannons.

These airforce manuals should explain how the cannons work and how they are constructed. I do not need originals, photocopies or scans on CD are welcome.

I am also interested in any Russian ammunition manuals and handbooks of army, Navy and Airforce in a caliber range of 12,7mm to 57mm.
All types of cannons: aircraft guns, anti aircraft guns, anti tank guns.

I am privately researching the Russian weapons and ammunition technology,
I also host an internet webpage at:
http://www.geocities.com/russianammo

If you have any documents for sale or trade, please contact me at:
russianammo@yahoo.com
(Please use English characters only, my email does not support the cyrillic letters .......)

I can either offer cash or other ammunition related documents of all countries and calibers.

Thank you very much!
