Gus Pech Foundry & Mfg. Co. Catalog No. 39. Previous owner's stamp to the title page states it was received in the "Vice Presidents office Sep. 30, 1918". Three additional office stamps appear on the title page. Interior is primarily clean and solid aside from the odd pencil notation, some dog-eared pages and some stain spots. The stapled card covers are in Poor to Fair condition; bumped and rubbed to extremities, moderately soiled with a 3.5cm X 1.5cm area of loss to the head of the spine/top left corner that "bites" a bit into the text block, smaller chip to the bottom edge of the spine. This copy was used for the purpose intended. Generously illustrated with fascinating photos of the Foundries products in action all over the world. Scarce in any condition.
