Ha! Probably better that it doesn’t. Since they were used on top secret spy kinds of stuff, if it told you, it would have to kill you afterwards. 😁 mikie

Bronze insignia didn’t come to be until 1902.  The infantry insignia appears to be for an officer, as there is no company letter.  EM would typically have a letter below.  There appears to be a maker hallmark on the reverse?  What does it say?   That hunting horn is not the typical US infantry design.  Looks foreign to me.   The 14th Inf, Arty and ME are all collar insignia - 1902 to mid/late teens.  Cap insignia was screwback.  Pinback insignia was worn on the collar.  

Welcome. There’s a good chunk of Frenchman on here I’m sure are able to understand you, but most members are in the US, so translation would be best. I’m pretty sure it’s as easy as dropping into google translate and the just copying and pasting. Welcome to the forum, would love to see your vehicles!

That’s an interesting use for one.

Sadly she is in really rough shape, pretty much scrap at this point. Too bad she wasn't recovered sooner.

I have had this wing for some time and was wondering if it has any collectibility. Made by Creative Casting Inc.. as stamped on the back along with a phone number. I have seen these in lapel size but never in a 2-3/4" wing. Any value? Thanks in advance.

The quality from my pictures is super bad. I'll text you the pictures on my phone and if it's still like it, I'll get some close ups for you.

Mickeys correct, green buckles  are basically the most common throughout the whole war, in high pressure liners that is. The. Black ones came pretty late and started to appear in theater probably right around late 44 early 45. At least that’s my understanding. Still at Tagt pint green was the most common. Is it your going to buy one get the green buckle.   

I think your good without any filler, doesn’t look like ethers nearly any putting and if there is , the paint will likely fill it in.

Depends on when it was put together. Until, I think, the mid-1980's, subsequent awards of the NDSM was shown by an OLC, at least in the Army. Then it changed to a bronze service star.
