Here is a closeup of the south German style ribbon bar worn by the Hauptmann with pioneer battalion 5 shoulder boards in the previous scan.
1) Prussian Iron Cross 2nd Class 1914
2) Bavarian WW1 Bravery Medal in silver or gold (same ribbon for the Max Joseph Order but no match with those recipients)
3) Bavarian Military Merit Cross 2nd Class or Military Merit Order 4th Class with Crown and Xs device
4) hindenburg CRoss for WW1 Combatants
5) third Reich 1938-43 Cross for 25 Years Civil Service
6) Hungarian WW1 Commemorative Medal for Combatants
Presenceof ribbon #5 indicates this Captain was a reserve officer called back up for WW2 duty and not a career soldier or an (E) Wehrmacht "re-tread." Probably dating from before the war, this illustartes that such a ribbon bar, if found alone, would NOT necessarily mean its wearer wore it on a civilian uniform (Railways, Post Office etc etc) since wartime reservists continued wearing their civilian awards on military uniforms. The same is true for officials of the Nazi party in Wehrmacht wartyime service-- see the "Nazi Kriegsmarine" scans.
