I don't think so. The stick is certainly not prewar as it has the pressed on threads as opposed to the early examples that are held on with screws.
I have not seen another example with these same markings. That is all I can really say.
Are there any markings on top of the can? Such as these. If there are not then I would say repainted. The can should show maker markings.

The Grenade is German. The markings I believe the 24 and the band are post war Dutch. BILLHi
Does anybody know if the paint is prewar?
