In 1885 the Canadian Department of Militia and Defence ordered 1001 Model 1878 revolvers from Hartley and Graham. They were all nickel 7 1/2 inch .45's. These were to be used to arm militias during the Riel Rebellion. How many were actually used at that time is not known. These revolvers were also issued to Canadian forces sent to South Africa during the Boer Wars. The MC mark was probably applied just after 1900 on revolvers used during WWI.
Condition: mirror bore, 95% nickel remains overall, 95% fire blue remains on hammer and trigger, some screws show traces of fire blue, holster is constructed of heavy leather and has been slightly altered, excellent grips, excellent marks, excellent mechanically.
