Hmmm... I just realized I'm batting around my self made uniform designations like they are standards that everybody uses! Sorry... I do that sometimes
Here is a quick overview of the 5 known BGS Sumpftarn smock/jacket types using the terminology I came up with:
1st Model Smock
2nd Model Smock
1st Model Jacket
2nd Model Jacket (sorry... this is a Polizei one as I don't have a pic of my BGS one online at the moment)
3rd Model Jacket (early badging)
3th Model Jacket (late badging)
