[John Fisher]

Looks like interesting theme with some perspective
Near it's a reference to a thick book about Bostons. It's in Russian but well illustrated. So I hope It will be useful.

Some strange references on the site www.armourbook.com - looks like banners spam, but the book is realy there.
Some bad news - the site request registration... in Russian as well So, may be another place will be found.

Another place for this book, but still need registration
The book about Bostons on www.69.by

In English one:
Military Chronicle, "Bostons" in Soviet Union, p.1. "Aviation museum serial"
But I can't understand if it's possible to download the book file from there...
