Mystery Bag, possibly from WWI
I picked this bag up at a yard sale last summer for 25 cents but have no idea what it was for or if it is complete. The loops look like they could hook onto a belt or webbing or be used for a strap. I do not think it is a gas mask bag as it is too narrow. I did what checking I could on the web but came up empty.
I'm guessing the PI S5 is a unit id although the S5 could be an officer's staff position technically.
It's in pretty nice shape, doesn't smell like mold or anything either. I'm hoping it has something to do with the US infantry in WWI and I can display it with my 1917 but if not, no big deal.
