My friend's parents have a small bard stacked full of manuals from tractors and planes. No clue where they got them all (has to be thousands) but it is their past time selling them.

Got the fast nickle for the loader manual, $130.00.

I found some very old Caterpillar heavy equipment parts and service manuals from the 1930s and they were something like $4.00 each. I think they sold in the 45 to 50 dollar range. I had 2 sets and they were for an old crawler track dozer and road grader. They were in pretty good condition for how old they were.
