The M3 SMG has a barrel length of 8 inches, that's about max for the 45 ACP.
I'm wondering what velocity I'm getting from my Uberti single action with the 45 ACP cylinder fitted.
Have to try some over the screens.

If the OP could pull one cartridge down so we could see the entire bullet,
and powder charge.
The charge weight would be helpful too.

I don't recall any 1907s, but I did not get into the actual Gun Closet except to pick up a shotgun to use to blow out a slag plug in our coal gasifier. Agency is TVA. TVA Public Safety, now TVA Police, is a serious LE agency to guard nuclear and conventional power plants, dams and in the past, defense plants for a variety of unpleasant materials; plus traffic on reservation roads, plus fire and ambulance service for installations.
I was a chemical engineer on the Muscle Shoals Alabama reservation, home of the then National Fertilizer Development Center, built around WWI US Nitrate Plant No 2 which was turned over to TVA for fertilizer work in 1933. Although there was defense work there for a long time after.
A craftsman at Browns Ferry Nuclear Plant was bringing me pickup 9mm brass from the site's range, they didn't mind. But that is drying up, nuke plant guards have gone to carrying slung M4s instead of pistols.

I hand load for several pistol caliber carbines. They are always loaded with the very slowest burning powder(s) appropriate for the cartridge and bullet type/weight. This is done to take advantage of the longer barrel length and gain a bit of velocity while still staying within the safe pressure limitations of the cartridge design. Use of these slower powders in a handgun would result in an incomplete and very dirty burn cycle, but would produce a really nice Hollywood muzzle flash!
I have a few boxes of WWII 45acp with mixed headstamps (4 or 5 different ones). But they are all early 1940s, and look like ball ammo from the era. They came back from Russia in the 90's. Story was that it was shipped to Russia in the early 1940's, and what they didn't use they boxed up and put it in tins. But they don't look anything like the ammo pictured by the OP.
If it were me, I would break them down, toss the powder, and reload with a known powder. And label them appropriately.
Yeah, that might be useful. Standard 45acp charge weights can vary from ~4.0gr to 10.5gr, but narrows quite a bit based on bullet weight. But I would still break them down and toss the powder out.

My Dad has an M92 Beretta that was supposedly a Browns Ferry guard gun before before being sold as surplus. Thats what the seller claimed anyway. Its got a "Z" prefix serial number, but no other special markings.

The oddest .45 was an ex-TVA Reising Gun that they traded in with all the other odds and ends for Ruger AC556 and Remington Model 870.

Funny to see this older post after posting what I did in the "pistol shots" thread earlier today.
Mixed head stamps in G.I. ammo, I have seen several times on government reloaded ammunition.
Though, I can't speak to that being the case here - for or against.
Non-pistol .45acp I have seen a lot but it was always (IIRC) marked *sub-cal* or *sub-caliber use only* for the sub caliber inserts to things like recoilless-rifles and such. So, maybe that is the rifle referenced?
Sometimes tracer for confirmation firing, sometimes ball for training purposes.
Again, I can't speak beyond anecdotally on this either.

Looks like you have several firearm suggestions, so I will just comment on the box. Manufactured by Olin and Mathieson Corporation would have been after 1954.
