So today i just bought a German canteen, but i’m a little unsure if it is a reproduction and/or when(year) exactly it’s from, i couldn’t really see any markings on the cap, bottleneck or the straps, i tried to take the cover off, but the buttons are a bit sticky, so i didn’t want to use force and end up ripping the cover. Anyways i hope some of you can help me.
