@waldoj things in my lab workshop that are this color:
Hardinge lathe
Moore jig borer
(Can't remember) horizontal mill
@waldoj you can get Wayne Moore's book in roughly this color, for an excessive price.

First Edition. - Hardcover - Moore Special Tool Company, Bridgeport, Connecticut - 1970 - Condition: Good - No Dust Jacket - Overall a good copy of this book, clearly used with some small cosmetic imperfections, but still held together well enough to get good use out of it. Stated first. Filled throughout with illustrations and B&W photos. ; Ex-Library, front paste down and free end paper have stamping at the top and pen written in the corner. Stampings say property of U. S. Army. The fep also has some very well done calligraphy saying "property of Cast Center 5600' in black ink. Some identification coding on the corners of the preface page, but otherwise free of markings. Spine/hinges have some loose spots throughout, but are still fully connected along with all the pages. No DJ, boards in good shape with minor edge wear. The spine has residue from a library sticker that was removed, does not appear to have damaged the spine during the process luckily. ; 4to 11" - 13" tall; 353 p. 15562 - Foundations Of Mechanical Accuracy
