These badges came today to me, They are all pin back and marked sterling, are they all ww2 or are there post ww2 models to?

Looks to be a combination of both. From what I can see you have 2 made by Fox that I believe are WWII. The first sharpshooter in the second row appears to have a hook catch rather than a roller which could make it pre-war. The one marked JK I am not sure, not framiliar with the maker. Those marked with a letter and number combination, i.e...G1, would be post-war. Those just marked sterling could be either WWII or post war.

 

There are several good threads on maker marks on the forum.
