ww2 usmc ribbon bars and badges?

[ww2marine]

I recently picked up a nice ww2 6th div. usmc service uniform named to a corporal W.G Miller. Everything looked great and as it should be, but I thought the ribbon bars and badges were odd. First off the ribbon bars are army 3/8 size. Second, there is an american defense ribbon with a a star in it. The uniform has a ruptured duck hd patch which i would imagine suggests discharge around 45-46, but there are no hash marks to indicate 4+ years of service. I also thought it strange that there would be a qualification badge with no qualification bars. The pistol sharpshooter badge has a different patina and no makers mark on back. In my opinion these ribbon bars and badges were collector add-ons to give the uniform a "completed" look but I know there are alot of oddities out there. Any help from you experts out there would be greatly appreciated.

looks like a silver star device on the ribbon...and why would he have a pistol qual badge but no rifle qual badge?

I'm wondering if our Marine replaced his other ribbons after the war. That GCM looks postwar, almost Korean era, to me. If that's an "S-21" on it, it's Susco/Harry Sugarman, BTW.

 

It's strange but not impossible.
