I can't recall that "mudpile," sorry Brent. I suspect my view would have been consistant with the above opinion. Apparently one of the major factors in choosing a shotgun to convert into a double rifle is the original proofing of the shotgun. Those with black powder only proofs could be suspect, those with more modern Nitro proofing are more attractive for such conversions. Stronger "magnum" proofing would be a plus, although not often encountered on older guns. The Sauer I mentioned does have Nitro proofs, and could be a twin of the gun pictured. It leads me to think there is at least a possibility the gun pictured might be more suitable than Mr. Show suggests. Just a possibility, I can't identify the gun either.
