A rather hard to find booklet which contains quality black and white photographs of Timken Steel, Timken Carbon and Alloy Seamless Steel Tubing, Timken Bearings, Timken Rock Bits, and Timken Fuel Injection Equipment, totaling more than 100 images, each with explanatory captioning. Book measures 6"x9". Cover shows light soil only. Pages are tightly bound and clean with the exception of a a smudge to upper corner of first page. Former owner penciled notes to blank page at back. Otherwise quite good.
