The gun is common enough, but how's about those red leathers on the gunner? Gucci?*
I'm doubting the provenance on those red leathers as something that would have been used in the field. Parade gear maybe.

* Reminds me of how my brother purchased a genuine pattern artillerist's haversack with strap some years ago. A garage sale seller's teen daughter had been using it as a purse! It was that clean and supple, despite being an actual wartime artifact. It was stamped "PATTERN" in white on the interior of the flap so was never employed in combat, but only rather something provided to leatherworks contractors or armory as a pattern for manufacture. At least my bro was in a position to recognize it and have it properly identified and confirmed, or it might still be found swinging from the shoulder of another teen girl in Michigan.
