Authentic WW2 German Flag?? Help

Hi, Im very new to collecting and having a hard time identifing fake from athentic items. I ran across this flag and bought it. The guy was a collector himself and said that he was pretty sure it was authentic and had it looked at himself. I have done research myself and I think it maybe real but still not sure. I was wondering if i could get a second opinion. I know there are bunch of fakes and repo’s. Any input at all would be great! Thanks!

It is a Nazi-German flag, not a German flag. Well whatever

Going on its condition, I would have to say fake, it would have had some signs of ageing or stains, tears, fraying, on the flag, now I know any thing nazi, the price’s are high, and because of this there are many repro’s going around, I would stay away from any thing nazi, unless its from a reputable dealer (if you can find one), what did you pay for it.
