"Hill's Patent" Stanley Bull-Dog Revolver: Blatant Patent Theft in 1878
This video examines the 1878 "Hill's Patent" Stanley Bull-Dog revolver, highlighting a case of alleged patent theft. The revolver features a simultaneous ejection system, which was actually patented by Jean Mathieu Deprez-Joassart in 1873. The video explains how "Hill's Patent" (number 3645 of 1878) relates to the lockwork, not the ejection mechanism, suggesting Hill claimed Deprez-Joassart's invention as his own. The gun was produced in various configurations and was manufactured in England.
