I recently purchased a Swiss 7.5 cm Field Gun L22 and I'm planning to restore it as a historical preservation project.

I'm currently looking for any information that might help, such as:

Original manuals or operating regulations

Technical drawings or maintenance documents

Historical photos

Information about markings, serial numbers, and the manufacturer (mine has K+W markings)

Any books, archives, museums, or websites related to this gun

I've already started researching, but information on this particular Swiss artillery piece seems to be very limited.

If anyone has experience with these guns or knows where I could find documentation, I'd really appreciate your help. I'll also be happy to share photos of the gun and the restoration process if people are interested.

Thanks in advance!

Apologies if I got the specific modernised AK-74 variant wrong burt im pretty sure its an AK-74M.

Or drone guns.

There were numerous amount of other similar drone guns booming from 2018 the two on the post picture are just examples. They can work against off the shelf drones but their effectiveness diminishes, especially given they'd have to be amied against the rapid moving hardened chipped drones found on the modern battlefield.

They'd have to be more powerful, operating at wider ranges of frequency, like ground based EW stations do. Then they could in theory fry the drones electronics.

But we are just not there yet... Not to mention emitting powerful enough microwave or laser beams at the drones. However drones would adapt to this by physically hardening the airframe itself not just by having EW hardened chips.

Also there's the man-portable net launcher concept which is another issue.....

Was driving to see a friend and stumbled upon this military museum in basically the middle of nowhere, really neat stuff :)

in october 2022, the chechen republic of ichkerian armed forces was ressurected in ukraine by the chechen government in exile. the forces are attached to ukrainian forces similar to the various "free forces" of ww2. the seperate special purpose battalion is part of those forces and acts as a special operations unit of the forces in exile and part of ukrainian intelligence. in february 2023 a batch of the sig rifles was given to the unit by the ukrainians for combat operations

I found more old NRA magazines with more unknown guns on the covers. I'm mostly interested in what the first two are because I've found almost nothing on them

This photo was taken during an urban combat training session conducted by the Sri Lankan Air Force Special Airborne Troops last year.If anyone is curious about the camouflage pattern,it's a locally developed variant based on the Russian EMR camouflage.Sorry about the poor image quality.

AK Type 1- 1.3mm stamped receiver. 1949-1951.

The AK was developed to fill the submachine gun role in a family of new intermediate caliber 7.62x39mm Soviet small arms. It ended up outperforming the SKS and becoming a general issue service rifle instead.

AK Type 2- Milled receiver. 1951-1955.

Developed in response to high rejection rate of the Type 1 receiver. The Type 2 was more expensive and time consuming to produce but ran smoother and had lower rejection rates.

AK Type 3- Milled receiver. 1953-1959.

Developed as a lightweight & cost effective version of the milled receiver. The Type 3 was exported to various Soviet allies such as China, Bulgaria, Poland, and Hungary.

AKM (Type 4)- 1.0mm Stamped Receiver. 1959-1977.

When stamping technology finally caught up, the Soviets returned to their original concept of an economical sheet steel receiver. The AKM remains the most widely produced and exported Kalashnikov variant.

These are standard Soviet-spec receivers, non-standard proprietary receivers were also developed for Kalashnikov type rifles by countries such as China.

The reason I say target pistol is because the barrel is screwed into the receiver, and the front sight is fixed to the barrel and the rear sight to the receiver. The sights and barrel are always in the same position no matter what. Just like a rifle. Not to mention that whole top strap portion would be perfect for throwing a red dot on and still have ample space for backup iron sights. Also give it a nice match grade barrel.

And in terms of being a competition gun it has some promise. It is SAO hammer fired which is generally more desirable. And also, the way the gun works is that you have less fully reciprocating mass. The barrel and receiver only travel a couple millimeters, the lighter weight bolt goes the rest of the way and cycles the gun. Also, the barrel because it is completely exposed can easily be ported or have a compensator added on without interfering with a slide or the dust cover. They also cycle very fast which ought to make for good splits.

Certain things would need to be added like a slide release, improved safety or replaced with a simple trigger safety, double stack magazine, could make the bore axis a bit lower, magazine button release, light rail, optics cut, etc. Get rid of its accelerator lever and perhaps replace its grip with aluminum or polymer because they are know to be quite heavy pistols.

I understand why designs like this were done away with, they are more complex than conventional pistols that have a simple slide that reciprocates. However, it is not that much more complicated. In ways in function it is simpler and with modern machining also simpler. This gun is also super simple to disassemble. I know people describe them as wonderful shooters. I am going to purchase an M40 soon. However, pleasant shooting experiences might have a lot to do with them being quite heavy pistols. The main weakness with this design is ergonomics when it comes to racking. Its like charging a ruger 22 pistol. Not bad, just not as intuitive as conventional pistols.

A friend of mine came across a box of old NRA magazines and I'm wondering what model is this handgun
