I've checked on there different times and found some. They're always on there & probably is where I'll buy a couple. Strange how the Garand M5's and M16 M7's are so common, but I guess the M14 which took the M6 saw limited use year wise.   It's a great gun, but I also collect FN FAL stuff, which competed with the M14 in the 50's in US military trials for adoption as our main arm and came close, but politically it was a little too close to WW2 for relying on a European gun maker in Belgium. 

My condolences to Eric's family and close friends. Besides Marine Corps and Working Dogs expertise, he was a fantastic contributor in other venues of this forum. He was a true wealth of knowledge about WWII forerunners of modern-day Special Operations units including 1SSFs, OSS as well as Merril's Marauders. I had the pleasure of adding several items to my collection from Eric. He also provided some great photos of 1SSF members and only asked that you contribute to a K9 rescue organization he supported. He will be greatly missed by many on this forum and will leave a gap in the knowledge base of this forum. God Bless you Eric Queen, Rest In Peace. Very respectfully, John

Does anyone know the WWII era squadron/group that this design belonged to?

Fantastic items. And educational!! Congrats

EBay?

That's the one that I was thinking of. Thanks! I think it's on my Aerial M5 with the early release lever, and I've got quite a few Imperial & Milpar M5A1's, so probably on a few of them too.   I used to have an M6 as my go to camping & hunting knife that I lost in my younger days. Been meaning to pick a few up, especially an Aerial M6 since it's a little less common of a maker than some. 

Hey Forum! Need some help in trying to date this paratrooper liner by Westinghouse.   Any help is appreciated.

Antique store pick up yesterday. Young Staff Sergeant with 5th Army patch. There appears to be some fraying at the top of the patch, maybe removed from another uniform and re-sewn to this shirt. I was hoping for maybe a bullion patch as I just saw the 5th Army patch and grabbed it adding to my selections, but when I got home and magnified it, it doesn't appear to be.
