Interesting MdI-Strichtarn set with rivet/jean-buttons

Found this interesting MdI stamped Strichtarn set.
It's nothing special at the first look but on the second one there are rivet-buttons instead of
normal ones.

The jacket is unissued.




The pants are used.



Made in 1.quarter 1990.

Nice Uniform. I think it´s one of the last ones dated D = 1990. i´ve no idea with the buttons.

MDI.
Volkspolizei.

I support this theory.
I suppose thet the empty (not dotted) field of the button is to distinct the NVA strichtarn uniform from the Ministry of Interior (MdI) ones.
