Thanks for all of the positive comments guys.

That would have been really special had Rigby made a new set of barrels retaining the original 450 barrels "as is". However, I am happy that it was at least re-barreled in arguably on of the most useful Big Game DGR calibers for a double rifle. I had been on the hunt for a decent deal on a .470 NE Rigby for awhile and was within a day or so of pulling the trigger on a very nice boxlock when I ended up getting this one for just a bit more. A Rising Bite Rigby is a NE caliber was a dream of mine. The incredible history that came with this one was all the more of a bonus. Needless to say, I am very pleased with it and feel very fortunate to be its caretaker.
