Narrative: The Rolls-Royce Merlin Model 31 was manufactured under license, in the US by the Pacard Motor Car Company. It was produced specifically for British aircraft and similarly for machines built in Canada, for example, the de Havilland Mosquito being constructed by de Havilland Aircraft of Canada Ltd. shortly before North America suppliers could be found for all the equipment required for the Canadian-built Mosquitoes. The first twenty-five (serials KB300-Kb324) were designated B.VIIs, and still had a good deal of British equipment fitted. The B.VIIs, had the Packard-built Merlin 31s driving Hamilton Standard propellers.
With the twenty-five B.VIIs completed, production began of the B.XX in 1943. this was similar to the B.VII but with Canadian and US equipment. A total of 245 B.XXs were built during the second main production run, and the first eighty (serials KB100-KB179 had Pacard Merlin 31s, the rest (serials KB180-299 and KB325-Kb369) had Pacard Merlin 33s. The first Canadian fighter-bomber version of the Mosquito was the F.B.21, similar to the F.B. VI but again with Canadian and US equipment and the Pacard-built Merlin 31. The F.B. 26 superseded this variant and but there were built (serials KA100-KA102).
