I received my copy of Lionel Trains O Gauge Volume 2: 1929-1936 a few days ago and what a magnificent work it is! The color photos are wonderful and, as usual, the text accompanying them provides great explanation/documentation of the piece. I cannot recommend in any stronger terms that every Lionel Prewar collector or enthusiast should have a copy. The wealth of knowledge in this book will make even the novice collector an expert. I bought mine through Brinkmannpub.com as no dealers in this area have it.
The only down side is now several pieces I had not planned on acquiring are now on my "Want List"!
