Not to get carried away with details, but some of what I posted this morning is questionable. I read a bit on Wikipedia and am posting an excerpt with appropriate accreditation if that is OK with site admins.
From Wikipedia..
"Between 1948 and 1968 Ford of Canada used the "F" prefix for Ford and "M" for Mercury. From 1948-1950 nominal tonnage ratings were replaced by a series designation in which the numbers indicate the GVWR when equipped with tires of appropriate capacity. Each code number is arrived at by dividing the GVWR of the series by 100. Thus an F-47 (M-47) indicates a GVWR of 4700 lbs. per axle or 9400 lbs. total for front and rear axles combined, F-135 (M-135) indicates 13500 lbs., etc. Each truck series is rated to its GVWR. In 1951-52 Ford of Canada got back in step with Ford USA with F-1 (M-1), F-2 (M-2) etc. (GVWR = Gross Vehicle Weight Rating - weight of chassis, cab and body, plus payload)"
Apparently Mercury lived on in the States for some time, but we are only discussing trucks and logging trucks specifically, because all the rest is of little interest.
I tried to make out the badging on the Ford logging truck and think it is 6,800, which would have been per axle. so 6,800x3 = 20,800 which seems about right for a three axle logging truck of that era not made by one of the specialty mfg like Corbett who made real trucks.
