The accompanying factory letter lists this revolver with a 6 1/2 inch barrel, nickel finish and smooth walnut grips when shipped on August 5, 1877, and delivered to M.W. Robinson of New York City. The left side of the ejector housing is engraved "Col D. B. Case/4th Pa." A period retailer or jeweler performed the inscription. As a member of the 4th Pennsylvania Volunteer Infantry, Colonel David Brainard Case was among several thousand state militia soldiers called on by the Pennsylvania governor to restore law and order to a violent labor dispute in Homestead in 1892. Known as the Homestead Steel Strike as well as the "Homestead Massacre" and "Battle of Homestead", the labor dispute was a defining moment in U.S. labor history as the incident dealt a major blow in the movement to unionize steel works. Colonel Case went on to fight in the Puerto Rico campaign during the Spanish-American War (1898). The barrel rib legend ends with "RUSSIAN MODEL." The barrel, cylinder and barrel latch feature the mismatched serial number "38303." Provenance: The Supica Collection
