1st Polish Parachute Brigade Insignia

[Abbekerk1]

Hi, in the spirit of trying to learn, posting here a polish paratrooper collar insignia from my own collection for thoughts and view. It is the metal version, and having looked at my reference books, I still cannot determine if it is a fake or real. The one thing that does stand out is that I cannot see a brass or copper base on the metal, therefore assuming that it is just one piece metal rather than flash coated, then it would indicate it is a reproduction?
2 piece construction, with the yellow overlayed behind and beneath the grey part. I note also the metal paratroop device looks like a seam down the side, almost like a sandwich or mold seam.

Thanks for any feedback,
