Measuring 12 1/2 inches overall, this bayonet was designed by one Arthur Pritchard, a British officer and Western Front veteran, who had a prototype fabricated by Wilkinson Sword and successfully sold gunmaking firm W.W. Greener on the concept. While the bayonet and the Enfield double action revolver made an impressive combination, Pritchard's design failed to take off, with less than 200 made and fewer sold. The blade is 8 1/8 inches long, bright steel with a "T" cross-section and a flat spine, fixed to the brass grip via a threaded and staked "rat tail" tang and a hexagonal nut. The hilt is one-piece brass construction, with a spring-loaded steel bar to lock the bayonet in place, and the cross guard marked "PATENT/No. 17143/16" next to an oval around "W. W. G" over an "elephant" (Greener trademark). These bayonets were numbered to the revolvers that they were hand fitted to. With a blued steel sheath. Notes from the consignor attribute this bayonet as an early example for use in weapons trials, and an accompanying letter of provenance indicates that it was purchased in 1961 from the director of W.W. Greener when they closed the company and sold off the remaining items in their inventory.
