Yes, indeed it is original Polish POS badge. Panstwowa Odznaka Sportowa - National badge of Sport Proficiency. It apperas to be in its bronze class (3rd class). Markings on the back prove its originality. The number 33 on the back signifies the edition year (1933). FSEF is its manufacturer. Warszawa - I don't think I have to explain it
PUWFiPW - Panstwowy Urzad Wychowania Fizycznego i Przysposobienia Wojskowego
