Here's a neat little paperback book published by Carborundum in 1940. Covers many aspects of grinding and sanding various objects using (amazingly enough!) Carborundum products. Printed in a 5" x 7" format, 100 pages, softcover. Lots of photos and descriptions. Good condition with a little bit of damage to the back cover. $10.00 postpaid in the lower 48 States, PayPal is fine. The best way to contact me is by PM. Thanks for looking!
