CHARLIE - Would those 50 parts be mostly engine parts or other parts used on the tractors? Might be time to stock up even more old CC parts!
TOM H. - IH put lots of those update parts in their parts & accessory catalogs. There wouldn't be part numbers & prices but I even remember IH Fire-Crater sleeve & piston kits for the older Farmall's being in them. Every season there would be one in the mail from the local IH dealer. The tractor focused catalog would be in late winter, the planter/tillage implement would follow a month or two later, then the mower/baler & combine issue a while after that. Then the fall harvest issue in the late summer/early fall. Then the interesting mail call would be the next year's BUYER'S GUIDE with EVERYTHING new in it in the late fall.
Back around the same time you had your catalog collection, I had a pretty good one too. Oldest IH brochure I had was for the 450 FARMALL, had the 460/560/656/706/806. Had some Allis-Chalmers, Oliver, and even a couple JD brochures. In fact I still have the 4010 brochure and the post card the local JD company store in Moline sent out in fall of '60 where they were displaying the "Brand New 4010-diesel". Seemed like a neat tractor until Dad bought a '63 model in '68. It was the ONLY tractor Dad owned I remember working on to keep it running more than I remember running. A brand new 756 diesel or 826 sure would have been a much better deal. Would have cost twice as much as the 4010 to buy but repairs would have been ZERO. Dad spent at LEAST the purchase price of the 4010 in repairs to keep it running over the four years he had it, 4 new tires, new paint, rebuilt electrical system, water pump, new clutch, major engine rebuild, new head gasket, and at least 2-3 injection pump rebuilds. All in about 1000 hours of running. The new tires, paint, & pump rebuild all happened before we took it to the field the first time. The tractor already had the 4020 kit in the engine in about 5 yrs & 3000 hours of use. Should have run like a new tractor.
ANYHOW, my brochure collection became MIA after our first move off the farm in Dec. '72. Was some time later that we went to look for it and couldn't find it. Folks did find my old baseball card collection from 1964/1965. I had maybe 40-50 cards, and the local baseball collector and auctioneer sold them for a little over $500. I had an almost perfect Roger Maris & Mickey Mantle rookie card in them which was most of the sale price. My brochure collection was in NO where near as good of shape. I studied that stuff, almost had it memorized. Every page was dog-eared.
