See how the finish is flaking off? I've seen that on some early stainless Winchester lever action barrels. They would not take a blueing, so they were painted with a special finish, which was usually a type of black lacquer. At the time this was called "Japaning". I point this out in case anyone tries to convince you to chemically blacken it. If you restore it consult someone who knows what they are doing and can replicate the old Japaning finish.
I don't believe it is factory original. Its always been my understanding that Winchester double proofed a barrel when it was sent back and they put a rib on it. So it is probably a Winchester rib but added later.
That would have to be a rare barrel.
Sasquatch is right. The rib posts on the 2-pin guns are made with the barrel.
I would like to see a 2-tone trap gun with a bright stainless barrel and blued receiver.
But that is just me.....
Hey Roger, Remember the M12 Stlss bbl that your dad had in the shop in Redlands???? What ever happened to that? Hey check out the footage a guy shot last weekend out at Kennys on a thread here called you tube goose hunting! It was a lot of fun--wish you could have been there! Phil SImms
From all the research I have done I have never found a receipt from Winchester that lists a Vent rib added to a gun. I have seen quite a few from Simmons but never any proof from Winchester that they added vent ribs to guns sent back to them.
In fact any advertising related to the "Winchester Special Vent ribs" States that they WILL NOT fit one to an existing gun.
They would add a new barrel with extension with a vent rib to an existing vent rib gun.
If anyone has proof that Winchester Service Center added Vent ribs to guns sent back to them, Please post it!
I have a build-up Model 12, in 12 ga., and the story that came with the gun was it was sent back to Winchester many, many years ago for a ventilated rib, but came back with the Simmons markings on the side of the rib.
Some research has revealed it is one of Simmons early ribs, by the words, and style of stamping from Simmons.
I have a 12 gauge, model 12 with a rib identical to a Simmons, but has no markings of any kind on the rib, and the proof marks are visible on the side as the factory rib guns are. This tells me it is a factory rib by Simmons. How rare is this? Do I have the only one?
That is a Winchester factory rib. At least two of the ribs that Winchester put on at the factory were ribs designed by Simmons and licensed to Winchester. According to Simmons if it says Simmons on the side, it was installed after market by them. If it doesn't say Simmons on the side, it was put on by factory, even though identical in appearance. I have a two barrel set,30 full and 26 WS1. Matching numbers. 30 full appears to be factory, 26 says Simmons. How weird is that? I sometimes think that there are no absolutes with these things.
