Bulgaria shoulder bords ID

[Valter]

I've been offered these shoulder boards and they should be Yugoslav. But they didn't match any yugoslav references I got, so I though they might be Bulgarian?

Any opinions appreciated!

the back side... Thanks for looking!

I've yet to see a Bulgarian shoulder board with that shape.... the ones I have are all six-sided....

Here's an example of a MVR Lt. Col. set

Thank you, Stogieman for your input! I'm just trying to eliminate possibilities. These boards (mine) are looking yugoslav, but don't fit any regulatuions.
