Millionaire Calculating Machine

Description
This is the mechanism for a direct multiplication, lever-set, manual non-printing Millionaire calculating machine. It includes a metal base, an iron frame for the base, and part of the carriage and the mechanism for entering numbers (but only part). Also present are a component used in direct multiplication, and two cranks on their shafts. The parts of the machine are marked with different numbers. The machine has no case or lid.
Stamped on the iron frame near the right front corner is the serial number: 4154. A mark painted on the carriage reads: 27-80. The number “27-80” indicates that the machine came from the collection of New York teacher and historian of mathematics L. Leland Locke (see accession 155183 and non-accession 1983.3003). Other parts of the machine may well be in non-accession 1983.3003.
According to the estimates of Daniel Lewin, a Millionaire calculating machine with serial number 4200 was made in 1915. Hence the rough date of 1914 is assigned to this object.
