I have a National Cash Register up for auction. This register is in working condition. You push the buttons and turn the hand crank and the drawer will open. I really don't know a lot about the register other than it is old. The drawer serial numbers match the register so its all original. The Serial number is 2068765. The tracer number on the bottom of the drawer is35004w and the register has an oak finish. This would be a great piece for any antique collector. If you have any questions feel free to ask. Thanks and happy bidding.
