Hauptmann in the 22 Pionier Regiment tunic

Hauptmann in the 22 Pionier Regiment tunic, early tunic with black piping around. Its a nice private purchased service tunic in very good condition, note - this is not a Reichswehr tunic or a Dienstrock - they are different in cut. This is a normal officers tunic, just with the pipings around the cuffs, front panel and collar. Very interesting tunic.
