Dear Yevgen,

thank for the work you have done. Bill is right, shooting down is easy but to proof it is something very helpful to others.

Last evening, when I checked my sources I wondered if it would be possible to post photos here in our discussions. That would be a great addition to our "problems". A photo can say more than 1000 words.

Strelts, what do you think about it?

cheers
Uwe

Dear Mike,

you can find Russian designs on:

http://www.viskovatov.narod.ru/T02/T02_02.htm

Unfortunately the text is in old (pre 1917 Revolution) Russian, so we are unsure how it will work with modern translation software.

Probably some of our Russian-speaking visitors will help you with the translation.

Best regards,

Strelets
