Thank you for warm welcome. I am a user and fan of rangefinders (especially made in CCCP).
As for the book, it's dirt cheap here in Poland, 15 PLN (~4 USD) a piece, but availability may be an issue. It is available in the Museum's
book shop, however they seem not to sell online anymore. You may e-mail them and ask. The website Lynn have found is another museum that sells it (here in English
). You could ask if they ship outside Poland.
