Don't think that is a paint scheme. Believe more shadow or dirt. I have the book and really enjoyed it, shame there's only the one photo. There wasn't time or real need to paint camo on new tanks at that late stage of the war, as it was long known on both sides how it was ending and the only issue was who would get where the quickest. I have seen some photos of post war Pershings with black/OD camo scheme.....Berlin Brigade company of M-26A1's used it in late 49-50, but camo patterns on M-26s are really scarce. I'd sure like to see some.
