Laminate Barrels

Art, the difference in patterns is because of the fact that, for some unknown reason, the barrel tubes are made from two sections, each roughly 15” long and weld-jointed together to form the full-length barrel tube. I currently have two that have this sometimes not very obvious feature. I’m not aware of any Parker-made Laminated Steel barrels any longer than 32”… but I certainly haven’t seen them all.

Or possibly 3 sections; obviously the thicker at the breech which is why the pattern if often slightly different
Hard to tell but the arrow may be the weld line between the sections
The other arrow is likely an area of decarburization from excessive heating during the helical hammer welding of the tube



The neat rib pattern is from the same laminated steel rod turned on its side and ground to fit
