I'm sorry to say but your great figure isn't a border guard.
In fact Schildkröt in Germany issued 2 similar outfits but they are not the same.
The one that you have is the police motorcyclist (Verkehrspolizei) or to translate exactly, "traffic policeman".
Here is mine on the left :
The second one is the Bundesgrenzschutz, "border protection".
Here is mine (the 2 outfits and accessories on the left are from the same set and the picture is missing MP40, green helmet, hand grenades, barb wire, 2 other colour karate belts and broken brick on its support).
The difference between both uniforms are the trousers style (policeman trousers like the VAM despatch rider whereas standard for the border guard) and the band with inscriptions on the sleeve for the border guard as well as stikers on the collars that are different.
Nevertheless it's assignment, your figure looks great and the uniform is in great condition.
