I picked up a 1944 D2 Traxcavator that has a Model TBA-2 Hyster Tractor Crane on it.  Along with the tractor/crane I get everything from the original order forms, Caterpillar build sheets, all books and documentation of all repairs.
My question is that the Parts Book for the Hyster TAB-2 Tractor Crane is a foldout of the engineering drawings.  I have seen few Hyster Cranes, and a few parts books, but have  never seen a parts book that is the engineering drawings.  Could this be a prototype, or were there just so few cranes put on Traxcavators that they never made a formal manual.. 

all of my cranes partsbooks were engineering drawings. and all were somewhat individuals as far as their manufacture even though the same brand. couldn't just call for parts on a 304 koehring.

Thanks bursitis, never had a parts book for a Hyster crane before.

 I have a Hyster product brochure with the specs for it,
