I recently acquired this flag (KM? 50×85). Therefore i would like to know if anyone could tell me about the markings, the authenticity of the flag and what kind of a flag it is. My best gues is that it’s a Kriegsmarine flag?

On the backside it looks like the Inkt from a KM battleflag got(printed?) into the cloth. Due time(laying on top of each other) or just a production error?(last 2 pictures).

Picures(the white is a bit more yellowish/dirty in real):

Thanks in advance! cool militaria

P.S. Sorry for my clumsy english :p
