Have you seen the book Engineering and Recovery Vehicles by Ampersand Publishing. Their website is the only place I have found the book. Not many real vehicles but some great ideas and kits I've never seen. Also Allied-Axis Tank Transporters of W.W. II. Great phots of the Famo and M25/26. I love engeering vehicles. Put an M32 on back of the Dragon Wagon. that is the way its displayed. Also, read the book Death Traps by Belton Cooper. Some photos. With 3rd Armored maintenance. Some have complained about the way the book was written, by repeating some things, etc. Really do not care, great book and learned things about maintenance going through France I never dreamed of.
