Badge for identification

[PREM]

This is most likely a fake, but I must admit that I couldn't find out who was this formation (or military school) , or who wore such badges. I searched, but it exceeded me ? I was looking to compare this fake badge with the original. If someone can help, I will be grateful!

photos from the auction ?
