I was going through some old GMC service bulletins and found an old one page (11"x17") Allis-Chalmers "General Information Construction Machinery Service Bulletin No. 105" dated January of 1957. It has general information (bore/stroke/capacities and lube types) for tracked vehicles, speed patrols, patrols, motor graders, motor scrapers and wagons. It's in pretty good shape. Free to first A-C collector.
Maybe you could scan it and send the scan to The Old Car Manual Project ? . They're always on the lookout for new and different things .
