Manufactured in the late 19th-century, these revolvers nicknamed "Man-Stoppers" were developed to do just that. Experiences of primarily British military officers and civilian personnel of the empire had shown that, when confronted with some of the native populations that were less than accepting of being colonized, many of the anemic smaller caliber revolver cartridges of the time just wouldn't cut it. These experiences of course also included all manner of local wildlife, which in many areas of the empire placed human beings very far from the top of the food chain. Their solution was a larger heavier bullet, leading to the development of the .577 Boxer cartridge, a shorter version of the .577 Snider and Martini-Henry cartridges popular in the military at the time which had proven their performance. The .577 Boxer packed a bullet weighing in at roughly twice that of the legendary .45 ACP and sent it down range at approximately only 100FPS slower. These revolvers were a direct result of needing a larger revolver capable of chambering the new .577 Boxer cartridge. This example was manufactured by Braendlin, who took up residence in Tranter's facilities and produced some of his designs, much like Tranter had done with Adam's patents previously. Braendlin's trademark crossed pennants over "B" is on the upper left of the frame which also has light border and flourishes of scroll engraving. The top of the frame is retailer marked "VAUGHAN & Co/39 STRAND LONDON" and there are standard British proofs throughout. The cylinder backplate is marked "TRANTER'S/PATENT" and "BRAENDLIN'S/IMPROVEMENT". The face of the cylinder, cylinder pin, front of the frame, and under the cylinder backplate are all numbered "4". It is fitted with brass bead and frame notch sights, a checkered grip, and a lanyard loop on the butt. This specific revolver is pictured and described on p. 242-243 of "Tranter Cartridge Firearms" by Black, Guerin, and Michaud.
