Strange officiers shoulder board

[LoCo]

This shoulder board belonged to an Estonian lieutenant. It has self-made red plastic borders - troop function color. I only have one period picture of him, and it seems that the shoulder board is the same on the picture.
Have you guys seen something like this before? Is it common?

[Adrian Stevenson]

I have seen similar ones before. I like it.

Cheers, Ade.

Thanks Adrian! Is it self-made for sure?

[Adrian Stevenson]

Yes, self made or "home made" (as we say here) for sure.

Cheers, Ade.
