These two trucks were new at BCFP Caycuse Div. as they were in the Cowichan area where I worked off & on from 1966 to 2008 for BCFP and the companies that succeeded them , I know these trucks and know where some of them went when they left the area . Each Company has its own system of numbers . With Fletcher Challenge a number starting with #40- was an Off Highway Logging Truck , #41- was a Highway Logging Truck , #50- was a Steel Tower Yarder , #52- was a Grapple Yarder , #54- Was a a Line Log Loader . #56- was a hydraulic Log Loader . Yes H-7 has a Cat 3408 in it since it was new .
