Gorgeous rifle with unique fuctions, features, and rarity. I hope if finds a good home. Only issue is having to go to a gunsmith to figure out the ammo.

This is one of my favorite of the toggle locks I've seen on Forgotten Weapons. Not to mention the finnish and the stocks grain.

love toggles! More Toggles! Thanks Ian

Man, if only I could find full photos of this thing. One of the most beautiful mechanisms I have ever seen on a semi-auto rifle.

That rifle has really sexy lines, what a neat operating system.

Beautiful rifle, and nifty action.

I'd love to see some high speed footage of this action

So many toggle action guns on this months, really like this mechanical joints.

This rifle is realy cool and unique.

I love the toggle lock action, its very unique and interesting

This is probably the best collectible sporting rifle I have ever seen form the era. And I don't say that lightly.

Satisfying action on that rifle. Just neat to see it. TY!

before i started watching your video's I thought for a semi-auto rifle you either had "direct impingement," some sort of piston, or roller-delay type action. You've really opened my eyes, thanks Ian!

Zee Chermans never cease to amaze me. Very cool concept, and quite fitting that Walther manufactured it.

that is just a lovely mechanism. As usual video is of great quality, thank you !

That is about the coolest looking action I have ever seen ! Thanks !

Having a semi-auto rifle seems a bit pointless if it only has a 3-round magazine, but I guess they wanted it to sit flush. I imagine the military trials version would have had a much larger magazine.

its a very interesting rifle,with a magnificent design

This is the coolest rifle I've ever seen.

Cool rifle and thanks Ian.

I love the simplicity of the action overall. It's certainly elegant in its own regard.

Great video as always, Iove learning about these unique guns.:D

Wow, I really like it. I wonder if anyone makes modern actions like this. That muzzle "brake" action is very unique.

What a gorgeous piece of machinery.

thats really neat. never seen anything like that. very good looking rifle

toggle orgasm right now, this rifle is insane! The operating principle is not that complex, yet the designer still managed to make it very complicated and interesting

Perhaps one of the factors in these guns not becoming widely manufactured was the fact that they developed most of them around the time of the Great Depression(1929-1939).The Great Depression is often seen as an American economic disaster but it really effected the whole world.Especially industrial countries that relied heavily on exportation.

Ian sure does love his toggle lock rifles

that is such a beautiful gun

That is one beautiful rifle, and I love how it's action works and looks. Very aesthetically pleasing. And idea on what gives the bolt that purplish color?

This action is so cool!

I love the mechanics of these older semiautomatic firearms, mainly pistols. But when a rifle has something unusual or unique im all in! I'd own this rifle if I had the money lol

Gorgeous rifle, Walther do make some pretty stuff. Would love to see a good nosey around a WA2000 at some point.

Seems like a much more sensible blow-forward gun compared to the other ratcheting Rube Goldberg contraptions. I would even say it's elegant! Since it's a toggle-lock, the actuating motion to break the knee can be of any direction as long as there's a perpendicular force acting on it.

More of this neat toggle guns!

Nifty mechanism

That looks fun to operate left-handed.

Ian looks busy..... so many reviews on so many weapons.... well least no fair use notification problems, many other youtubers have still problems with that and youtube seems lost on the subject. XD keep it up !

possibly a 9x57 mauser or 9.3x57. those had bullet weights near the proofing, and were sporting cartridges

The toggle action caught me off guard. I thought this was gonna be like a G41 at first.

Interesting design of the rifle

I love that the toggle lock is on the side

Rock Island must love Ian's "free" marketing. I wonder if it effects the final auction price having something like 50k views on this page.

Walther guns are just elegant, plain and simple.

Teutonic engineer in me = Geeked. Big Bore Lover in me = Geeked. Old world craftsmanship,styling in a futuristic (back then) design. Would love to have a rifle like that.

It's a shame there aren't many rifles like this left.

Wow this is the only video I can find on this rifle. At least on yt

Could it possibly be chambered in 10.3x60R Swiss?

SO cool!

My best guess would be a 10.3x57 Mauser. Second guess would be a 10.75x57 Mauser, but that is less likely as a nominal 350 gr bullet was used. A chamber cast would be required to be certain, but I suspect that isn't going to happen.

Damn that's one smart mechanism

Very beaytiful gun !!!!!

what a wonderful rifle. realy cool. i tought p08 too-

What a beautiful gun! Ian, do you know why toggle-locked arms never caught on, beyond the Luger? They seem to me an excellent way to build a gun.

That is so cool.

ian you've probably heard this a lot, but a stoner 63 video(preferably a long one) would be amazing.

this is probably the sexiest rifle i have seen for a long time.

reminds me of a Browning lever action (that could be adapted to this type of toggle action, but with an internal toggle that forbids a lefty shooter).

Having an op-rod that pulls in tension instead of pushing in compression seems a good deal smarter, all other considerations of operation aside. Have there ever been gas piston arms with enclosed pistons that stroke forward instead of back? I'd imagine fouling of the muzzle device to be the major liability here, or at least a real concern.

This one is very interesting indeed.

will we ever see a flame thrower on the show?

Except for the back end of the action, it’s a very attractive rifle.

Holy smokes! As a left handed shooter, that bolt would be an eye opener... Or, in the worst case, and eye closer, lol!

This rifle is fucking beautiful.

Damn that is cool!

Very cool

"It's a little less expensive" Estimated price: $35,000 to $60,000 Yeah, I'll jump right on that. Really cool video and firearm though, it looks like a slick system for an early semi-auto rifle.

It sounds almost as if there are two different microphones picking up sound in this recording. Anyone else notice that?

Kind of a gas trap Grand Luger hybrid. Very cool but looks like recoil impulse would be funny feeling toggling to the side but who knows.

Ian, please do a show of a European sporter rifle with double-set triggers or point me to a previous video. I feel that setting trigger systems just don't get enough attention as they are very wonderful as aids of accuracy. Your vids are auto-liked without regret every time! : )

I just love togle lock guns

It looks like you're showing the rifle you shot those two deer with.

I realize the design was not overly successful, but that is a beautiful action @.@

I wonder if residual gas pressure in the barrel is meant to play a role in cycling the action after the toggle knee is bent.

Hmmmm, a gas operated gun not susceptible to carrier tilt. I like it.

Camera angle is alittle high... Love your videos.

St.m.G stands for "Stahlmantelgeschoss", which is indeed the German word for "full metal jacket".

There must be some way to gauge the chamber to determine the proper cartridge dimensions!

Have you ever reviewed a Browning Recoiless? Relatively modern (~20 years ago) design but flawed and obsolete now. would love to see you review one.

one cool gun. i wonder what happened to the project, most of the sporting rifles are 2-stroke manual operating.

That's just freakin cool :)

Hi Ian, first of all thanks for the interesting clip & sharing this nice rifle with us One question came up: i never knew of a Swiss Rheinmetall company. From all that i know Rheinmetall is a german manufacturer, and always has been (located in Duesseldorf with their first production site in 1889) I heared they have bought Solothurn AG (swiss manufacturer) after world war one, or at least sharings of the company - so they would be able to get around the versailles treaty and continue development of small arms at that time. Karl Heinemann was a german engineer for Rheinmetall. Do you have more details about any swiss involvement in this rifle? Keep up the good work :)

Rheinmetall is a german company located in Düsseldorf, Nordrhein-Westfalen. They are manufacturing the cannon-barrel of the german "Leopard-2" Tank. Definitely not a swiss company ;)

Rheinmetall is basically a German company. Top location is Düsseldorf. Maybe, they had in the ´20s a location in Switzerland.

That's gotta have a really strange recoil impulse.

Bet that would be scary as hell to shoot for us leftyys Ian

the quality is nice. i guess this bleed over to there airguns as they produce some high end very accurate air guns..

I would love to see that action in slow motion

I reckon it was conceived to be a boar or deer rifle. Pretty hefty round, a few follow ups in the mag. Seems plausible.

Hi Ian! I was wondering if you hunt? If you do which kind of rifle do you prefer?

Ian, That mechanism kind of looks like the Japanese Trials Gas-Operated Pedersen Rifle that you did a video on earlier this month. Both are toggle locked with the "op rod" going forward. Do you think there was any relationship?

Quick question Ian. Do you find buyers using your videos to inform their bids? Or are they more knowledgeable about the weapons than even yourself?

The toggle cover is an interesting idea, and the toggle unlocker is much simpler than a Pedersen's. Wouldn't this kind of system be very sensitive to dirt or mud in the front of the rifle though?

That seems like it would be a super-reliable mechanism. Any thoughts on why it wasn't more successful?

I would call it the German Rheinmetall company, because of the military limitations of the Versailles treaty after WW1 they used loopholes in Germany to work on guns, hence using a third party country to work in since it technically did not violate the limitations of the treaty. Not unlike tax loopholes in these days. :D Also St.m.G. probably means "Stahlmantelgeschoss", aka full metal (steel) jacket.

hi, as far as i know, rheinmetall is a german company, wich, in order to work around the versailles treaty, bought a swiss arms manufactur company called Solothrunes AG. i dont know if thats related to this gun, but i never heard about a swiss rheinmetall.

could you slug the bore and see if you can figure out what cartridge it fires

5:03 now I can use what I learned in mechanics at University

Not a lot of cartridges in that diameter. Fewer were commonly jacketed. 10.75X57 Mannlicher is all I can find, so probably a likely candidate?

Interesting design, but being left handed, I'd worry that toggle would hit me in the face.
