Mystery Machine I got no clue...need help to identify.

Did you try putting it together without hammer/tapered anodized installed.

If you can get just the tank to slide into receiver, there will be a gap between the barrel and valve tophat. That will give a clue how long the projectile could be for loading.

The oring seal doesn't want to fit into the hole in the black tapered slide...if it did there's no way to release any compressed air when fired anyway, the entire assembly would just fly out the back tank included when the sear is released nothing to hold it in, there is no valve in the tank just a hole that leads into a cross hole about an inch in. I don't see how this thing even functioned...if any type of compressed gas was fired through the slide it would just disipate...there is no seal between the barrel and the slide hole...this thing will not and never did propel anything out that barrel configured the way it is. The tank and the slide don't appear to have ever been mated together no marks of any kind. The stainless screw was ground shorter??? There is some kind of fouling in the barrel will investigate in time....Still have no clue...

The wasp or hornet is probably the key that would lead back to the manufacturer, may have been out of business for decades. Someone may eventually recognize it.

The two pieces in the picture below do not fit together? Don’t worry about the tapered anodized piece right now. The piece with the oring IS the valve stem (top hat). When it gets pushed into the tank, air comes out the center. Look at an airforce valve.

Ok...it's beginning to make sense now thanks to you...the two screws, attach the tank through holes in top and bottom of receiver and the slide fires back to actuate the valve...projectile loaded through the hole in the slide...I guess

The sliding anodized piece id is beveled to hit the yellow seal to actuate...the silver extention doesn't move and acts like an extention of the barrel to position the projectile to the bore...now what gas and how to charge it...next question...

Correction the silver piece IS the barrel.

The tank almost looks like it's multiple pieces? The cutout for the little silver BSPP fitting looking thing looks like maybe a piece slides over the other? Can the tank be disassembled any further?

Yes, I never saw a HPA vessel like it..I tried to push the valve but may be pressurized, only have one attachment screw so can't try dry firing yet...but at least I understand how it works now. Will proceed with caution. Thanks everyone...doubt if I ever would figured it out...lol.

Good!

So as you can see now, the distance between the barrel and tophat give room for loading.

The transfer tube should be pushed forward to load projectile and cock the hammer. Then moved back against tophat before firing.

Does the transfer tube have orings internally? To seal it to the tophat and barrel?

The oring on the top hat at present may be just there as a shock absorber.

Cool stuff.

No orings just a through hole except the yellow shock absorber one...in the above pix the gun is cocked and when trigger is pulled the sliding tube hits the yellow bumper to fire so the way it appears now is how it would fire I guess???

In the picture it is cocked and ready to LOAD. It is ready to fire when the sliding piece is pulled up against the oring. Upon firing, the hammer flies back and hits the black sliding piece. Which pushes the valve open momentarily.

Looking at these 3 pictures....top, the gun is cocked with the sear engaged with the gap to load ready to fire....center, with the slide against the oring the trigger has been pulled sear disengaged....bottom, nothing on the slide moves independently, it moves altogether...no way to pull anything back to the oring without pulling the trigger, must be foward to engage the sear...the entire thing is the hammer.

That’s interesting. The Airforce type guns the hammer is independent of the transfer tube. This allows closing the tube after you cock it. It will work the same if it all move back together. The fact it doesn’t have orings in the transfer tube means there probably isn’t much drag to impede the hammer action.

When you figure out what size screw it takes to replace the missing one, if it’s a number series, it would kind of indicate US made. Maybe…?

@RM100GUY any further information on your mystery gun?

The "thing" is locked away in it's case...I doubt if I'll ever look at it again. It's not a thing that interests me and my wife sure isn't going to find anything out about it...If a world wide chat fourm can't figure it out I guess it's not very important...I do appreciate everyons efforts!

Wife thought she was doing a wonderful thing for my hobby and the thrill of winning it at auction...even though she doesn't know what a pellet is...I have to keep that in mind...have to keep it as a trophy! I did my due dilledgence trying to figure it out...I still have know idea as to what kind of gas it takes or how to charge it or if it's even safe....If I knew more about it I would fix it up for her to experience shooting it...doesn't seem likely though....last few times I ask her to shoot she declined...not her thing and never was...she will eventually forget about it...
