I have seen Vickers built barrels as the photo above shows markings of. I owned a Parker PH with Vickers built barrels. They had similar markings, but read a tad different. Mine read "ESC Vickers & Co."

However, I have seen some barrels on Parkers that were monoblocked using Vickers tubes. These have had "Vickers" on the bottoms of the tubes along with proof markings.
