Rib matting and cut barrels

[David Noble]

I will dig out my tools and properly measure the chokes tomorrow. I do know that they are very tight.
After looking at the barrel flats I'm seeing something that makes me think these barrels were already made up at the factory and were modified to the current configuration to fiil the order for the gun. It looks like a hole has been filled in where the extractor retaining screw is usually located. The gun was ordered as an ejector gun, and they didn't put that retaining screw in barrels that had ejectors. Here is a picture of the flats. Notice the slightly different colored round area between the lugs. Also showing is a Remington service code of ASS 3 which is March 1947. There is probably no way of ever knowing what they did at that time.
I am working on additional pictures now.
