Hello. Can you help? I am trying to undertake historical research into a specific development in early Russian aviation. The topic is multi-speed propellers that operate like changing gear in a car when driving up a hill. I need to contact an English speaking Russian who has a deep knowledge of Russian propeller research. Can you supply me with the e-mail address of someone with whom I can correspond? (I only speak 'Google' Russian!). Thank-You. Andre ROUSSEAU pyralog@yahoo.co.nz
