Barrel ME is less than 0.

I have a similar non-import Type I WINCHESTER sans "W" and "WP" long skirt barrel but with "P" stamp on top of barrel 6 1/2 inches below muzzle, flaming bomb with an "F" stamp above integral gas cylinder on left side and an "A" stamp on the flat side with a muzzle gauge reading of 0 that is on a Quality Hardware receiver.

Neither Ruth, Duff, Riesch, or any other authority mentions these factory USGI WWII WINCHESTER barrels that were never stamped with the "W" and or "WP." Riesch states that:

"ALL barrels show the manufacturer's name or code behind the front sight."

Obviously, this is not an absolute fact. There are no doubt more of these WINCHESTER barrels out there that prove the exception to this supposed rule.

You need to show pics of your barrel.
There are a few other possibilities other than it was just missed on the stamping. As I posted on the cmp forum, they stopped using both the W and the WP proof and used either just the W or the WP later in production. If you are a Carbine Club member you can read about this in the 6&7 million SN WRA update written by BQ97 from here on this forum.
Accidents happened is the markings of carbines see the post a few below here about the no name carbine.

Dave,

What are these other possibilities? This Winchester smooth barrel has not been turned on a lathe to remove manufacturer or import markings. The barrel's width measurement is spot on with WWII USGI specs. When Riesch stated emphatically that "ALL barrels show the manufacturer's name," he is not making allowances for these "accidents." If later in production means after 43 or 44, those barrels would have the short skirt, yes? But the later date production barrels still would not account for the absence of either mark. Receivers missing the manufacture's name is indeed an anomaly, but barrels missing a manufacture's mark should not be that unusual or mystifying as compared to a receiver.
