I have a complete set consisting of a small mechanical adding machine, its original accompanying instructional book, and a sales pamphlet, stored together in a fitted case. The Machine: A compact, oval-shaped nickel/silver-toned metal pocket adding machine with three columns (ones, tens, hundreds), operated by three brass-tipped studs and a single reset knob on the side. Numbers 0–9 are engraved along the top face. The machine is stamped "PAT. JAN. 8, 1878" on its face. It appears mechanically complete and does function fully. Surface shows age-appropriate scratching and patina. The Book: A Practical Treatise on Cancellation and How to Cancel, a small red leather-bound volume with gold lettering on the cover. Copyright February 1882 by Charles Creigh Fields, printed by the Transcript Printing Co., Springfield, Ohio. Published and manufactured by Peel & Elster, Springfield, Ohio, 1882. Contains the instructional and mathematical text for operating the machine. Book condition is worn — cover intact with gold lettering legible, some interior pages torn at edges. The machine sits in a fitted compartment built into the book itself, forming a single unified object. The Sales Pamphlet: A promotional pamphlet from the Bristol Novelty Company, Incorporated, Louisville, KY (organized 1892 under a Tennessee charter to manufacture articles invented by C.C. Fields of Bristol, Tennessee). Contains a biography of inventor Charles Creigh Fields (born Russell County, Virginia, 1849), promotional description of the machine, and customer testimonials dated January 1893 from sources including the President of King College and Dominion National Bank, both of Bristol, Tennessee. Pamphlet is incomplete — cover page and first interior page are missing. Remaining pages present and legible.
