This tunic was period time modified by a tailor due to the personal taste of the owner. Soldiers preferred the more elegant M36 style featuring a dark green collar, dark green insignia and a vertical pocket bar. All modifications were executed period time and definitely prior to 1945.
Modifications like these are quite common and give this tunic a unique touch.
