IBM Model 24 Card Punch

This gray desk-sized machine for punching cards to be used as computer input has a table with keyboard at the front and a card hopper, card bed, and card stack at the back. The keyboard is cabled to the punch. Cards move from the hopper at the top left, down into the card bed, across the bed to the left, and up into the stack on the left side. It is possible to punch individual cards and to have several cards programmed to be punched identically in some columns. The model IBM 24 does not print data entered at the top of the card.
A mark on the punch reads: IBM 24 (/) CARD PUNCH. Another mark there reads: PROPERTY OF (/) INTERNATIONAL BUSINESS MACHINES CORP. (/) 024 30864 SO.
