Many British officers assigned to Africa and India chose Lancasters as their personal sidearms, but the total production of these pistols is estimated at just 712 further subdivided into smaller volumes in the various calibers. These powerful multi-shot pistols were also popular among the explorers, hunters, and adventurers who wanted more stopping power when facing man and beast in various corners of the British Empire. The top flute of the barrel cluster is signed "CHARLES LANCASTER PATENT. 151. NEW BOND STREET. LONDON." and has a blade front sight, and the left flute is marked "455 CF." There are Birmingham proofs on the barrels and frame. The breech face is stamped "CHARLES LANCASTER PATENT" in a circle. A later "PP7" marking is on the back strap. The trigger guard does not have the usual serial number marking. Instead, only the factory assembly number "5" is stamped on the bottom right of the barrel, frame, and some internal components suggesting this may be a very early example born out by the locking catch being of the earliest type, perhaps a factory working prototype. The butt is of bird's head type with smooth walnut grips, a lanyard ring is present at the bottom of the gripstrap.

Very good with 20% of the original blue finish and otherwise smooth gray and brown patina, some minor pitting, and moderate overall wear. The slightly undersized grips are also good and have mild dings and scratches. Mechanically excellent.
