Victor Automatic Calculator

This ten-key electric printing adding machine has a brown metal and plastic frame with brown keys. The block of nine number keys has a 0 bar below it, and a subtraction bar and a blank bar to its right.. A lever is in the right front corner and a red button in the upper right corner. To the left of the number keys are a clearance lever, a N (/) R lever, and a lever for which one setting is x. The place indicator is over the keyboard, and the printing mechanism, carriage, paper tape, and motor behind it. The machine allows one to enter 11 (possibly 12)-digit numbers and print 12 (possibly 13)-digit totals. In addition to numbers, the printing mechanism prints decimal markers and labels on both the right and the left of the numbers. A serrated edge helps to tear off the paper tape. The brown rubber cord is separate.
The model number is 76 86 54. The serial number is 2930-987. Dated from Smithsonian tag number. Walter J. Smith, who was a supply technician in Exhibits Production at the Smithsonian’s National Museum of American History from February 1979 to September 1994, used the machine.
