Joe, their salesman described it as a "non" so I took his word for it. The chamber length is a puzzle as well; I've seen these with 2 5/8 or 2 7/8, not 3". How could one know if it is original, presuming it has only BP proofs?

The high hammers do make a difference in the ambience of the hammer gun. I may have to throw away my 10 gauge hulls and loading tools and so have to stop looking at these things...
