Hello!
For what it is worth there was a Soviet book about making wooden airplanes which was translation of a British book (or report) plus apparently some indigenous chapters (paint technology). I have some copies at home, but don't remember the title now. The book was published in 1945.
Is it possible that the famous "delta-wood" used in Soviet designs has connection to the molded plywood technique developed by Lockheed at USA? Also in Germany compression molded wood was used in propeller blades (middle section of blade) already before war. IIRC that had conenction with USA (patent?).
It is also interesting that Soviet Union received 784 120 lbs phenol formaldehyde as Lend-Lease deliveries (plus 36 556 252 lbs phenol and 1 119 800 lbs formaldehyde). Phenol formaldehyde resin - better known as Bakelite - was used as adhesive for delta-wood and normal plywood. How big was Soviet Union's own production of these strategic materials?

These are some short thoughts of mine of this very interesting subject.
