GERRY - Thanks for posting all those pic's. I spent WAY too much time around late 40's & early 50's vintage medium duty trucks when I was young. They were wore out but still being used as farm trucks by many people around home. Wouldn't have been s bad except the brakes on those over-loaded trucks were not good when they were new. Rated load capacity didn't mean much to most farmers back then.
The IH cab-over, third pic from the bottom always amazed me. Local feed company ( small town of 103 people I grew up by had THREE feed mills, bank, restaurant, tavern, gen'l store, big lumber yard, local garage that worked on cars, tractors, other farm equip., also did some general machine shop work, three trucking companies, a fertilizer co, and an elementary school and a church.
ANYHOW, the one feed company had one of those cab-over IH tractors for a while to run down to the Kent Feeds plant in Muscatine, IA every day to haul home bagged hog & cattle feed suppliments. The two small lower front windows always made me laugh. IH really did make some off-beat trucks thru the years. Basically that model was a cab from a conventional dropped onto the frt fenders over the engine to shorten the wheelbase so longer trailers could be pulled. And That was back in the day when 32 & 36 ft trailers were the norm. Just about the time 40 & 42 footers were starting to be made. 45 footers were still several years off.
