Internal sleeving reversing.

[Double Play]

Hugh,
It would be my guess the chokes would have been removed as a straight sleeve inserted into a straight cylinder bore would be the easiest way to get the job done. As Channing said if removed you would most likely find the original reason for the sleeves and it might not be pretty. If it were me and I wanted to proceed with this project I would send the gun to Kirk Merrington and get his opinion.

Larry,this was what I suspected ;a large part of the value would be the gauge[14] but this has been radically altered,only a process like Teague relining could restore the gauge and then it would still be "messed with" .Probably will pass on this restoration effort.
