Collar Tabs

I think that these collars are real ones but they are belong to one of Eastern Block countries, not Soviet Union.

I think they´re bulgarian.

I think also it's bulgarian. I have a picture of a border guard collar tab, it's the same insignia (but not the same quality). I guest for a milice (police) officer if the piping is silver, may be some internal troops if the piping is gold.

The collar tab concerning this thread is not here, but it´s the same style. I think it must be for parade or walking out dress.
