ID these GI .45 pouches?

[NC Rifleman]

Ran across these while unpacking some boxes from the good ol days. Was hoping someone could help me ID them as far as what time period they're from,"M" model number, etc. Did some online searches and didn't see any like these. The green one has the loose weave type material on the front and the rear part is tight weave type. There are no markings on the material or fittings. I put the US on the flap after finding a stamp a while back. I'm pretty sure it is an actual USGI item, several of them were found in an arms room at Ft Bragg a few years back. The tan one is made entirely of tight weave canvas, clearly USMC marked and has PHILADELPHIA and some numbers in the blacked out areas beneath. It used to live at Camp Geiger. Thanks for your help.

If I remember correctly the Tan one is a WW1 vintage and the O.D. is WW2 vintage.
The main difference besides color is the botom of the pouches and how they are sewed shut.

I have examples of both in my web gear stuff.

Thanks for the reply. I was pretty sure the tan one was early, only one I've seen like it. I thought maybe pre-WWI since all of the other WWI era pouches I've seen were the type that aren't all tight weave material. The OD one pictured is made exactly like tan 1918 marked and dated ones I have. Also I've got tan M1923(?) WWII dated pouches that are constructed like the OD VN era pouches with single center snap, which kinda threw me since I thought OD color came later in WWII and I didn't think they'd go back to the twin snap configuration, but I guess they had a lot of variables then.

May want to check the size mags it fits as the OD one looks like the pouch for two 15 round M1 carbine mags.

They're both definitely .45 pouches. Have one of the similar carbine pouches on my M1.
