Amateur collector, ex-cop, gun nut and currently a military contractor that helps design and test new weapon systems. I have 10 years playing World of Tanks on Xbox.  I recently inherited some uniforms that I think have historical significance. I'll post some pictures soon and see what you think.

That was super helpful. You nailed it. I think the texture/construction  of the flag threw me. Thanks for the help atb.

There's a long post in the WW1 category all about First Army WW1 SSI. It shows examples. Yours has a badly proportioned orange device that represents Signal Corps units assigned to First Army. See the aforementioned post to verify.

I attended the monthly flea market today. I am proud to say that despite seeing a few militaria things I would have otherwise wanted to buy or at least ask the price of, I walked away without any of them! But I did find this nifty brand new straw hat for only $5.00 US! I needed a new hat and this was perfect.  mikie

Exactly! I have never seen this one before. Maybe atb. The symbol looks orange to me, which might be consistent with Signals. But I would have expected crossed flags or something. Moderator, senior moment. I meant to put this in the patch section. Please feel free to move it.

There was this guy in my Infantry company mid 80's. His last name was Klinkenbeard. Back in the day in High School, there was a guy on the football team named  Richard Long. There once was a Man from Nantucket.... Never mind..... I noticed something back in the day when we used to have to stand in line to get paid. The guys whose last names started with A... Got paid first!  

Thank you!

Nice patch.  I’ve never seen it before.  What does that “device” signify?
