Nah, they're the ones that I'm sure are WW2. I are 99% sure that they belonged to a (named) soldier in the Artillery Bn of the Piron brigade (I bought them with his dog tags). Besides, I don't think that any were produced in Belgium in the immediate p/w period ('cept the German produced version with the pins), but if you can tell me otherwise, I'm happy to be contradicted
