"taper choke bored for smokeless or black powder"

1908 Sears Catalog: "Shooting qualities- As before explained, the shooting qualities of these guns are unequaled for long distance killing, long range shooting, for penetration, pattern or target. Both barrels are full choke bore, so firmly constructed that unlike other guns, there is no recoil or kicking. That which in other guns goes into recoil in the A J Aubrey gun goes to give greater force to the shot."

Crescent Triumph in the 1898 Sears catalog. In early 1895 Crescent introduced its first hammerless double, the Triumph Hammerless, made in 12 gauge with either 30" or 32" Damascus or Twist barrels. The gun was based on patents issued to William Beesley and controlled by Charles Lancaster and was the only boxlock hammerless double ever made by Crescent.
