The Mercury M-Series was a range of pickup trucks introduced in 1946. M-Series trucks were largely rebranded Ford F-Series trucks mostly sold in the Canadian market. M-Series vehicles were designated by their Gross Vehicle Weight Rating, divided by 100. An example would be the M-47, with 47 referring to the truck's 4700 GVWR. The M-series was available with a range of inline six and V8 engines during production, which lasted until 1968.
