Prior to 1854 Britain had supplied military defense for Canada but at that time the British Military was so heavily embroiled in the Crimean War that they were hard pressed to maintain their own military forces and therefore asked Canada to become more active in supplying their own arms. Canada accepted and in 1855 a commission was sent to England to purchase arms for the militia. Among other purchases, they bought 800 Colt Model 1851 Navy revolvers with 556 going to Upper Canada, the area of Canada now known as the Province of Ontario and 255 being issued to Lower Canada, the area known today as the Province of Quebec. The revolvers were issued to cavalry units, the markings on the grip show that this Navy went to the First Wentworth Troop, trooper number 7. Now looking for more information on this troop.
