6.5 X 43 IWK | Cartridgecollector.net
6.5 x 43 mm IWK 1962 XPL
In order to fit in a standard 7.62mm NATO action length and mags, a cartridge using the 121gr Voss style 6.5mm projo with a nose length of 4.1 calibers (27.5mm) dictates a case length of no longer than 43mm. A 6.5x43mm cartridge using this long projo would require a casehead dia. of at least...

Yeah he is, but the photo provided does look like a bad photoshop. A Chauchat magazine adapter was developed for the Lebel rifle, but it was mounted horizontally, not vertically. I think Huon may have just made a digital mockup based on the assumption that the Lebel's magazine adapter functioned exactly the same as the Berthier's.

Speaking of Chauchats...
The PM Chauchat-Ribeyrolles, developed in 1918 for the French Army. This gun was reportedly conceived for Saint-Chamond and FT-17 tank crews and was built to a compact size, without a buttstock, so that it could be fired from the tight confines for armoured vehicles. It was called a "Pistolet-Mitrailleur", i.e. 'Machine Pistol', which was the French equivalent term to Italy's "Pistola Mitragliatrice" (the Villar Perosa) and Germany's "Maschinenpistole" (the MP 18,I).
The first model was basically just a cut-down RSC Mle 1917 rifle converted to fire full-auto. The second model, made in 1919, was a little more refined and more resembled a compacted Chauchat LMG. It fed from 20-round CSRG magazines, which was probably not a wise choice as they were extremely poor, but were some of the only box magazines that were widely available to the French at that time.
The Chauchat-Ribeyrolles concept was abandoned after the war, as the requirement disappeared. Huon described it rather generously as France's first submachine gun, though clearly it was not really an SMG on either a technical or doctrinal level. Nonetheless it was probably the first purpose-built Port Firing Weapon (PFW) ever made.

That's the version for the Schneider CA1 tank.

" When you look at early invention in the semi-automatic, you get some interesting-looking firearms. The first attempt at the semi-auto pistol was Borchardt’s C93 that attempted to reinvent Maxim’s toggle lock. Around the same time several other inventors were attempting similar yet different designs.This Passler & Seidl Semi-Automatic Pistol is a rare representation of those guns. Patented In 1887, this firearm was invented by Franz Passler of Otakring and Ferdinand Seidl of Budweis in Austria. This early repeater played around with the self-loading features of a semi-auto. The ring trigger could be manipulated forward and backward to load the firearm. The ammunition was loaded into the bottom of the frame. The caliber is 7.7 mm and may be a 7.65mm Borchardt cartridge or an 8mm Bergmann tapered rimless cartridge (two contemporary cartridges of its time).This pistol was made only in limited numbers. The design was modified slightly by Gustav Bittner of Weipen, Bohemia, who produced limited numbers about 1893."

Tula State Arms Museum's write-up about the Schwarzlose smg. It doesn't appear to say when the gun or it's sibling were captured, which is what I wanted to find out

Googling around a bit, looks like as of 2014 it was at the Tula State University, Max Popenker of world.guns.ru sent a series of photos over to Forgotten Weapons under the name of "Experimental German 08/18 Maxim Submachine Gun". And that one is slightly different (as the linked article says) from the one documented in the report, so at least two must've been captured.
And for some updated content: I briefly talked about the 12.7x108mm 6P62 way upthread three years ago, but about six months back a Russian user on Reddit posted some more information on it. Fully quoting his post:
If I understand his subsequent reply right, the pictures of it are all from a weapons and technology expo in 2014, being demo'd by Spetsnaz "Vympel" group. No relation to the Baryshev delayed-blowback action as I'd been speculating, which is a whole other mess worthy of its own post. ZiD = V. A Degtyaryov Plant, for reference. And what maniac thought the airborne VDV would want a 40lb full-auto anti-materiel rifle, neither of us could figure out.

Japanese paratrooper rifles, from top to bottom Type 100, pre-production Type 2, Type 2.
The so called “Type 100” was actually an experimental take down rifle based on Type 99, it did NOT have an official name. It utilized interrupted thread to lock the barrel and the receiver, which proved unreliable during testing.
Early Type 2 added a locking wedge that strengthened the connection, however it kept the detachable bolt handle which could be easily lost in the field. Moreover, it had a permanently attached folding bayonet under the barrel. The final Type 2 canceled both features, and proved satisfactory to be used by paratroopers.
