Originally 41-20084, this C-53 was NC15574 and N70B before coming to Canada in 1955 as CF-HXS for Shell Canada. Sold to Quebec Cartier Mining in July 1958 and later re-registered CF-QCM. Note, this aircraft had a Hiper DC-3 conversion in the past with P&W R-2000 engines and new propellers for improved performance, especially single engine performance. You can the the slightly longer prop shaft that maintains clearance with the fuselage. Sold to British Holdings in British Columbia in 1979, it was cancelled from the register in 1980.
