Thomas Boss & Co. was located at the address on the revolver in 1862-1908 and is still recognized as one of the leading makers of fine arms today. The revolver features fine English engraving throughout consisting mainly of scroll patterns along with some accents. The barrel has a blade front sight, Birmingham proofs flanking "450" on the upper left flat, and "T. BOSS & CO. ST JAMES'S ST, LONDON" on top. The top strap groove and notch at the rear of the frame serve as the rear sight. The left side of the frame at the breech has "W. TRANTER'S/PATENT/54870." The cylinder has Birmingham proofs and rope style border near the front. "26" is on the bottom of the barrel at the breech, back of the cylinder, front of the loading gate, and right side rear of the frame. The grip is finely checkered and has double line borders. The revolver comes in a hardwood case fitted to the gun with an empty cartridge block and oiler inside.
