I'm a little reluctant to post on this subject and show my ignorance of doubleguns, but let me mention something though I really doubt it will be relavent to this case. With muzzleloaders (my area of study and collecting) doublebarrel shotguns were often choked in the right barrel and cyl bore in the left barrel. The reason was because it was easier to reach up and cock the right hammer for a second shot than it was to reach over the right hammer to cock the left hammer. Assuming we are talking about this SAC Gun being very early 1900's (see, my ignorance is showing!) could it be possible that it was ordered right hand choked because the original owner was used to a right hand choked double hammergun?
