Advice on DDR uniforms

[Esteban_cool]

Gents,

I finally found a militaria store at Osaka where I`ll try to get a DDR jacket this weekend. However, since in that store I found very nice copies of all kind of stuff (German WWII awards, for example) but also some original things too, I am doubtful about of the authenticity of it. So the questions are...

Which details should I take care of to know if the jacket is original or not?

Are DDR uniforms of middle-low rank already faked or altered? (BTW, the jacket shoulderboards belonged to a unterleutnant or some close rank.)

Any help A.S.A.P is appreciated.

Finally, I could get some pictures of my recent adquisition. Opinions welcome.(BTW, I didn`t know that collar tabs were metallic.) Shoulderboard`s pics will come soon.

Enjoy,

Esteban
