"[The book] is very interesting as it contains data about Russian losses. Thanks that it is a valuable supplement to the article of Eichiro Sekigawa "The Undeclared Air War" in Air Enthusiast edition of May-July 1973. This article is also comparing a course of fights and verifies data of Japanese side. If you do not mind, I attach the tables with data on Nomonhan.
