Do any of these gas cylinder screws appear to be Winchester ?

I would normally guess the two with the machine lines, but as I understand it both Springfield and Winchester can have machine lines. Mine just doesn't. And my Winchester screw does.

Attachment 33411Attachment 33410Hard to determine which is Winchester, the Dulite color and machine marks might indicate Winchester. Also note the slot is still new without being distorted in a really bad way

[browningautorifle]

Mine has no real finish left and has some distortion. It came from a scrapper front end that had the lug cut off and the gun altered to 7.62. It's just my guess because of the machine marks, it has been pointed out that some SA screws have marks too. I haven't seen them.

Jim, I have not seen them either that I can recall, some Winchesters have the punch marks or thats what the Winchester experts claim

[browningautorifle]

I guess I should take some pics and post them here. The one on the left is the Winchester. I forget what serial range the gun was. The SA is in my LL328219. It's hard to fit an M3A1 tool into the SA. Too tight.

Attachment 33432Attachment 33431Jim, This is not the single slot but one of the second type used for grenade launching,
these are around but still not common. I would say that factory rifles were not issued with this screw as it came with the early launcher.

First I've seen. The type that you had to fire a ball round to close?? The one I have in the 7.62 is a P small hex, Elastic Stop nut co Union NJ. I think it's a small hex. Doesn't matter. Standard stuff. Yes, the first ones came as a set apparently. Launcher and valve.

My Winchester has a punch mark.

Type 2 is what spent most of the war with Grenadiers. Yes the Poppet style was in production, but grenadiers already had the type 2 and most never got upgraded. That is why the Poppet style was marked with a P, to tell the difference.

Sometime after the way Rock Island had the responsibilty to find the non closing type 2's and pack M7's in sets with Poppet styles and sights.

SA made approx 36,000 type 2 around the fall of 1943. Not many exists today.

Mostly all that were found were modified to Poppet style right after the war.
