DDR - black Strictarn?

I have found here is such jacket. The First once see Strictarn on black background.
I have not found in internet similar. Possible that this DDR. Who carried such form?
The Armorers?

This is overdyed with black ink. You can tell because all the light gray pieces are black. It also looks like civilian buttons were substituted for the light gray plastic military buttons.

Unfortunately some surplus wholesale companies think overdying things they can't sell makes them sell better. I remember my horror at seeing 1958 Belgian Jigsaw camo trousers overdyed in purple color!! This was at a time when they were quite rare. I cried

I have a similar item, overdyed blue, looking like some kind of "night/urban" Strichtarn jacket :-)

According to I have understood, in the DDR standard is also used campaign dyed black to make them work uniforms.

I think it was a common thing in WP-armies to spare with uniforms. The old, used clothing, was recycled that way as working, or in some cases also as combat clothing. When I served in the Hungarian People's Army (1988), such overdyed green combat fatigues were given to some of my comrades - they looked quite odd wearing deep-green (overdyed)shirt with trousers faded fast to white ...
