Here's a few things in my collection without tearing everything apart. CASE/Bacharach diesel service tool kit, most of my 400 parts books plus a shelf of service manuals, a box of wooden foundry patterns and a hydraulic "Supergauge" for testing hydraulic pressure. The gauge is about 6-7" in diameter. I've been collecting all things CASE since I was 12. I'm 33 now and also have 14 CASE tractors, over a dozen plows, 2 disk, grain drill, corn planter, corn picker, corn binders, grain binder, thresher, field cultivators, stalk chopper, ect.
