I once shot a Parker with 24" factory barrels. It was one of a set built for a Doctor on the upper Eastern Shore. I am certain that they had been ordered that way, not bobbed by Bob the gunsmith. Since I shot the short stocked gun poorly and not being educated to the value of rare Parkers I passed on the set. Not one of my brighter minutes, I must say, in hind sight. Oh well, you can not buy them all and I would have certainly sold it long ago for some other must have gun.
Chuck the gun you refer to may have been the same one but this was a set of guns to shoot Skeet. I doubt that they were broken up as a set.
