WWI era photo of AEF troops in France, the doughboy in the front middle has a Grenade vest

The 3 armed triangle is a UK military acceptance mark, sometimes called a crow's foot.  The 1944 is the year the scabbard was made/accepted into service.  The "8" under the left crow's foot is most likely the inspector's mark.   I've seen lots of "mismatches" or "cross-matching" knives and machetes.  Whether it is truly a mismatch is debateable.   As to "mis-matching", in reality, you use what you have.  Thousands of machetes (and tons of other stuff) were made and sent to the UK during the WW2 under the Lend-Lease program, as well as the US buildup for European action.  Scabbards were made and issued to those who needed them.  The same model of scabbard might have been issued for several machete models.  Maybe the US sent machetes and no scabbards so the Brits had them made.  Maybe a US soldier "liberated" a nice leather scabbard while in England, or a British soldier said. "OOH, look, an orphan machete.  I have a home for it."    Without documentation, you just have a nice 1250 and a nice leather scabbard.  I have a nice shelf for it if you want to get rid of such a mashup. 😁

This looks AI enhanced.-generated. Boehm only wore jump wings at this time as a qualification badge. I assume the insignia on the beret was a USN officers small eagle and crossed anchor and what we see here is AI generated. Most of the original phots I have seen are not clear enough tp make out the beret insignia and are black and white. Here is Boehm around the same period

Those are called Sword covers.  The sword and scabbard are slid down into  it and either stored in that manner or slid inside a leather sword case for transport.   They are different lengths to accommodate swords of different lengths.   They would have been used for almost any type of saber or sword that fits them.  I  got one with my Texas A&M University etched M1902 Army saber in 1973.   I also got one with my M1852 USN Officer's Sword along with the leather transport case in 1977.  Other than one is a dull gray and the other a dark grey, and a couple of inches different in length, they are identical to your two.   The wider mouthed style is "probably" designed for a bell guard, as are on M1852s, or multi-knucklebow hilt style as found on the M1840 cavalry saber.  A single knicklebow hilt, as found on the M1902, only need a narrower opening.

the first patch looks like one of the Mexican made copies sold on wbay a few years ago. They were painted on pig skin peppbled leather and had stitch holes added to appear uniform removed/worn. The Mexico faker did all kinds of CBI patches and other patches.   The 14th on purple silk looks to be a good chinese made one but hard to see the details in photo. The bullion CBI looks to be a Paki fake anf the embroidered 14th looks like a copy.

Hello Great tiger jacket! I'm going to receive one, I think it's a reproduction! But which branch of the military wore it? I'm looking for information on this model, patches, etc.! Thanks     PS: I'll take more photos once I receive them.
