Possible East German Army jacket

[ice]

Hallo

I was given this jacket some years ago by a friend. I want to believe it is East German Army. The one photo shows the only tag in the collar and it says " K52" One photo shows the stencil mark on the inside pocket and the third photo gives a general view of the chest and pocket and shows the unidentified colour patch. Can somebody correctly identify it please ?
