Gem Adding Machine - wood cube version

An uncommon wood case version of the popular Gem adder. The box front has a label with the 1904, 06, and 07 patent dates and the maker’s address, “Gem Adding Machine, manufactured by Automatic Adding Machine Company, 319 Broadway, 1-3-5 Thomas Street, New York”. A tag on the faceplate of the adder repeats this information. The closed box forms an approximately 4 1/2” cube. While the mechanism is a typical 7 digit Gem chain adder, the case is totally different - a front plate screwed to the wood box. The 7th number wheel has lost it’s numbers and the 4th wheel has skipped a cog, reading one number off. All chains are intact and move freely.
