Something doesn't add up here, Bill. You say they are Parker Reproduction barrels and Kenny says he checked into them when Chadick had the gun for sale and they were non-Repro barrels.
Maybe you can go over to your neighbor's place with a bottle of wine, some good old cheese and a digital camera, explain to him what's up, take some good macro photos and post them up for Mr. Skeuse and the rest of us to see. Mr. Skeuse can then comment on them and clear things up regarding these barrels . . . it might even lead to a wonderful Parker Pages article. Let's get on it, eh?
