I've looked at so many versions of this badge that my eyes are blurry! I don't see one that matches mine exactly. There were probably many different suppliers of this badge, but, still....There are ones with between 5 and 12 (which is mine) vertical bars in the shield. Mine is the only one I see that has the "E" in E Pluribus Unum on the first section of the ribbon. All the others I see have the "E" right next to Pluribus. The 13 star cloud over the eagle's head on mine is a bit oval, where most of the more modern ones are round. Lots of variations of the quiver of arrows, eagle's neck, attaching points, etc. Amazing how many versions they made over the years, and from several different countries too. From the ones I've seen, it seems to more closely resemble the WW1 versions (if I can believe the various poster info). If anyone is an expert in these things and can narrow it down a bit, I'd appreciate it.
