Mystery Receiver? HELP Please?

Nothing like it in Desperate Measures.
I would suggest that it used a tipping breechblock. If it had an operating slide it would have had twin flat operating rods, one on each side. The operating handle would have been attached to an operating rod.
H&R made an autoloading rifle called the "Ultra" that was set up this way, had bottom lugs not unlike this one. This isn't an H&R, but the general layout is not dissimilar.
It is always interesting to see something like this, something that is a mystery.
 
The other parts may be in the box of stuff, would be interesting to dig thru.. They probably would be finished similarly and look strange.
 
Stab in the dark....again. There once was made the grossest semi auto civilian rifle. I believe called the "Standard Rifle?" A semi auto made in the USA, 1920s or 30s. It could be shot pump action or semi auto by however means. It was the ugliest rifle I have ever seen, past or present. Either the forearm OR buttstock was METAL! Bronze or something like that.
It was a financial flop....I wonder why? :D

I vaguely remember it being reveiwed, in a 1977 Popular Guns magazine....

On further research, perhaps an experimental rifle on the "bang" principal, gas is bled of at a nose cone "trap" which explains the lack of parts on the barrel.
A sliding sleeve covers the barrel and actuates the mechanism.
If one has a copy of "Thatcher's Book Of the Garand" there is an early chapter on post WW1 semi auto development & the Berthier rifle, page 38, submitted in 1920 for trials at Springfield Armory looks the closest in my opinion.

PS How long was the 8mm Lebel round?

I have one of the "Standard Arms" semi-auto rifles with the brass pump/fore-end, in .35. What is in the photo is definitely not one of them.

Wow dude, that is an old rifle...
Thanks for the reply, I thought I was the only one in the world who has seen one of these rifles.....
Sorry for the ugly comment, .35 calibre is kind of cool.....

The chambering is too short for a M41 Mauser or M41 Walther from WW2.

Most people look at me kind of strange when I tell them I have one. I have the Model G which was the Semi auto version. There is a gas cut-off on the gas block. The pump version was the Model M. They are certainly not common.

This one is not mine, just one I found on the net.

Mine also came from the land of beer and lobsters (and deer). Maybe they were a downeast favourite.
 
Barring that it's some kind of one of a kind prototype or project, I can't see it being ANYTHING but a lever action with a clip/rotor fed mag.

I mean come on, NO piston/gas tube or even a hole in the barrel for a gas block and if the cartridge it fires is anything bigger than a pistol round then blowback is a no no. So it isn't semi/full auto.

There is no place I can see to manipulate or lock a bolt for bolt action.

It could possibly be a type of pump gun...maybe....but I'll stick with my lever theory.
 
Ljungman, the only smi-auto rifle cartridge it may be is one operating on the between wars, on the 'bang' principal.
With muzzle cap and all......many were made in prototype form for the Allied powers, as they trialed some in the 20's and 30's.
Then the M1 Garand design came along, and left them eating dust!

PS thanks for the backgrounder horseman, neat idea in a deer rifle, for it's time!
 
Guys, I think does have a rotating 4 lug locking system. Behind the ejection ports there is a round milled area internally(not shown in the pics) that it looks like lugs may rotate into. Looking into the rear of the receiver looks something like an o with a + on it. The bolt would be 2 pieces with the rear section having a "plus +" shape that rotates into the round milled area while the front round section chambers the round. I'll take better pictures when I get it over to cast the chamber. Maybe I can somehow show the inside of the receiver. It is supposed to be here by Friday or saturday again for the cast. Pretty strange unti though. Gotta love a good mystery! GRIN

Well, the crude chamber cast was just done this morning. The chamber dimensions are somewhere around 39 to 39.5 mm long, 12 mm at the head, 11.4 at the shoulder, 8.97 mm at the neck. Hmmmm. A 7.62x39mm cartridge is a bit sloppy in the chamber and sits a bit too deep in the chamber but is definitely the closest thing I have found yet. The bore measures at .319 inch groove diameter and .308 land diameter. O.K. after all that, anyone have any suggestions. I'm still lost! Ha! ha!

O.K. Guys, we started checking rounds this morning to see what fits and lo and behold 300 Savage chambers PERFECT in the darned thing BUT it is an 8 mm barrel, so it looks like it is either a prototype rifle, never completed or a totally custom built wildcat that some gunsmith was working on. I'm doubt that the internal machining in the receiver is within the scope of the backyard gundmith though. Regardless, it is definitely a strange piece and likely will remain a mystery. Does anyone have any idea how to go about registering a barreled receiver that doesn't exist as well as a caliber that doesn't exist either? That should throw 'em for a loop at the registry! Ha! Ha!
