Opinions on greatcoat

[paul.j]

Hello all,
I have this greatcoat, I had originally thought it was maybe Czech re-issued but am now thinking it might actually be a post war BW? The markings are rubbed out, making think deception, and also look to have had a tag glued over them, what I can see looks to be OSM? 1/2?.
Any opinions would be appreciated.
Thanks
Paul

It could be West German Bundesgrenzschutz.

He's right.That's exactly what it is. A BGS mantel.

Thanks. Do you happen to know what those letters OSM, if that's what they are - bit unclear, mean?
