Not a repro, but still post-war:
This is an old uniform coat of the Bundesgrenzschutz (BGS) stripped of insignia.
Notice how traces of the sleeve shield with the federal eagle and the rounded "BUNDESGRENZSCHUTZ" title above it are clearly visible.
Ahhh, BGS, very nice...I didn't realise how close the early post-war BGS stuff looked to the war time equivalents - I've only ever seen the 60s style BGS overcoats which look different. Thanks for the swift reply!
