TIM Calculating Machine

Description
This incomplete stepped drum, manually operated, non-printing calculating machine has an iron base painted black. The rest of the case is missing. The eight data entry levers are linked to both number dials and brass stepped drums. The number dials record digits entered. Levers in front of the dials zero the entry. An addition & multiplication / subtraction & division lever is on the left, and the operating crank on the right has broken off. There is a cloth and plastic cover for the machine.
A mark on the right side, under where the carriage would be, reads: 02274. A mark on the left side, under the carriage space, reads: 1446. A mark on the bottom of the machine reads: 1607. A number painted on the bottom of the machine is 27-71. This is a typical catalog number of the Museums of the Peaceful Arts in New York.
A TIM carriage with Museums of the Peaceful Arts number 27-91 may well have come with this machine and has been placed with it. The carriage has a nine-digit revolution register and a sixteen-digit result register. The number on the carriage at the right front edge is 03282.
The object is from the collection of L. Leland Locke.
