RE: Looking for reference material for Pershiong
Danny, Here are three listings of good publications;
M-26 Pershing Walk Around series by David Doyle. Squadron Signal 5706
The M-26 Pershing & Variants, Troy D Thiel Schiffer Military History Book, Atglen, PA
M-26-M-46 Pershing Tank 1943-53, New Vanguard by Steven Zaloga. (* the name is misleading as the M-46 was named for Patton)
The Pershing didn't use much camo at all. In WW II it was too late and during Korea, not much camo was used outside of camo nets.
There was a unit that did use a white patch camo scheme in Korea, winter 1951, but I don't know the unit nor did I see any there. Pershings and the M-46 Patton were all a plain-Jane OD with regulation Geneva Convention stars and white block letter ID. My unit had M-46s and used a yellow triangle on the turret with green unit numbers and white stripes on the gun tube to ID the company from the air, but otherwise, straight reg markings and no camo. (my avitar)
Hope this helps. Are you planning to do a Pershing? Which era, be glad to help.
