William Evans produced double rifles on commission throughout the early 20th century, primarily for clients who visited the Pall Mall shop and needed a safari outfit. The William Evans Double Rifle in 470 NE is a properly regulated London double rifle built to the same barrel standard as Evans' shotguns, regulated at the factory to ensure point-of-impact convergence at 50 yards. These guns are uncommon and underrecognized outside Britain.
