Yup, DelGrego's files are by name, not by serial number. This is not likely a rebarrel. When DelGrego got a request for a skeet conversion, he would normally saw off the original barrels, stamp with the skeet in and out choke markings, and install ivory beads, front and center. Of course we would not do that today, but those were different times. If these were "leftover skeet barrels", they would be post Parker Brothers, Remington manufacture, and would have no Titanic Steel logo on the rib or "T" on the flat like on this gun. This is a very common skeet conversion, probably with sawed off barrels, and well worth the asking price. By the way, any original skeet barrels would have the beavertail forend lug which this gun does not have. I'm sure any potential buyer would also like to see the choke stampings on these barrels also.
