Soviet Transport Aircraft since 1945 by John Stroud (1968, Book, Illustrated)

This book is no longer in print, but if you can find one, it is an outstanding reference for Soviet commercial aircraft from the Li-2 to TU-154. It is especially useful for modeling, particularly VEB Plasticart model aircraft from the former East Germany. It has many pictures of prototype and concept version of Soviet airliners. Many pictures I have never seen anywhere else! Also, rare pictures of interior cabins and flight decks.
