M1941 heer wool tunic

[paul w]

I am looking for a "so called 1941" tunic. The 6 button variation of the all FG Wool heer tunic that was made in 1941-42.
I thought that these would have been very common as many 1000's must have been made as the Heer expanded for Barbarossa. However, other experienced collectors state they are the rare. (Most lost in Russia and only made for 1 year or so.)
Most of the survivors seem to have been altered by having green collars added as walking out tunics (that were kept at home?)
