I’m sure it’s post TR, but some help on identifying it would be greatly appreciated. No MMs other than what is shown. Thanks

What do the experts say, Post-war? I have seen a lot of varieties, some with metal fasteners; I am leaning towards DDR. Any thoughts? Thanks

screw cap shows WW2 era markings. Everything else is post war.
Maybe DDR/NVA used up some old stock screw caps?

Anybody else have an opinion?

Postwar bottle. Use cork with war supplies.

Looks more like a Postwar West German Bottle to me. You could buy them in the Scouts Supplies Shops.
