I ran across an interesting book at my local Barnes & Nobel called "The M26 Pershing and Variants: T26E3/M26ּM26A1ּM45ּM46/M46A1" by Troy D. Thiel (ISBN: 0-7643-1544-7). The book is similar in size to the Squadron Signal in action books but about twice as thick. There are 81 pages and except for the first 7 introductory pages that have technical data on the various models, the rest of the book is full page photos of the tank. Some are in action photos of the tank, others are detail photos of various display tanks. All photos are in black and white.

There's a two page spread of a Dragon Wagon pulling up a knocked out M46 in Korea in June 51. Book ran $14.95, not much more than a Squadron in action book.
