It could be that the ejectors were installed by Parker and someone at some point obscured the barrel steel legend and blued the barrels. The work on the barrels seems cruder than the ejector work.

With that serial number you can bet the barrels are either Damascus or have been sleeved.

Or they are barrels from a later serial number

The installation of the stop plate isn't quality work and I would think Parker Bros. would have filled and filed the extractor rod limiting screw.

Regardless of the barrel steel, shouldn't there be a "D" or some other stamp indicating the barrel steel on the flats? Would there be any other full S/N stamped on the forend iron like on the underside of the metal? We might find a partial S/N on the ejectors or other small parts, not that it would help much. Maybe a good magnifying glass could determine the original S/N on the forend.

Good points Chuck.

The forend wood, if original, would have the serial number stamped in the recess for the iron.

I was thinking sleeved barrels as well. It is hard to tell from the photos, but i do not see any clear signs of it. Maybe just a little bit of lightness in the bluing in front of the barrel flats.

Sleeving barrels prior to the early 80's was done by soldering the replacement tubes in place thus producing a visible seam and thereafter tig welding was introduced in the process where the seam could be hidden when rust blued. However,if the breech is Damascus, rust bluing will not hide the cast iron wire. Damascus barrels were popular until post WWI so if Parker did the work you would think they would add a wear plate when they replaced the forend iron for the ejectors. I think the serial # on the barrels was filled in and restamped and # on the forend iron matches the serial # on the barrels, anotherwords the identical set of stamps were used.

A very good executed solder joint can be just as undetectable as a welded joint. And, rust blue does hide damasuc pattern pretty wellupon initial inspection. Generallly it takes looking at it at certain angles in certain light to see the pattern. The amount of bite in the rust blue solution used also has a part in it too.

The serial number stamping on these barrels has been redone by the look of it. And the bolt bite has been welded on.

The left barrel enhanced appears to say PAT ? APRI and the disappears from the photo
