Thanks so much for the info and comments!   I was hoping to find a roster and AxolotlHelmet  hit a home run on that, thanks!

Apparently a separate firm and not Waterbury Button Company if that's what you've been looking at. According to Bazelon &McGuinn's "American Military Goods Dealers and Makers", they made brass buckles and buttons. Established in 1837 but not incorporated until 1876. They report the backmark is found on post-CW eagle buttons (apparently this one), Albert's GI-98A5.

Great flag!

Very sad to hear this.  What a gentleman he was on the forum, and generous and kind with his knowledge and insights.  A great loss to the community.

A Korean War era Sergeant around 1952-53, clues, the Collar discs on shirt, these came into Regs in late 1946, then the OD Tie OD waist web belt, these come out in 1948, rank is just Sergeant via the EM Grade restructure of 1948.

I would agree to the assertion that all of these men were part of Company G, 112th Inf Reg, 28th Inf Div as I found Eddie Patton (1918-1978), George Penny (1912-1980), and Joe L. Tanner (1925-1997) listed in a 1945 Document (awarded the GCM) attached below. I have hyperlinked the above veterans with their findagrave pages as well.   Furthermore, we can actually semi-date this piece to when it was signed as Stanley E. Babiak (1917-1991), per his WWII vet compensation application, was only overseas from April 16, 1945 to  August 3, 1945. This record has also been attached.   Hope this helps!

This is a late WW2 production M1C but used in the KW.

Here are a few Vietnam era Special Force quilted patches.
