Remington Adding and Subtracting Typewriter

This is a combination adding machine and typewriter. The upstrike typewriter has a QWERTY keyboard with two shift keys, a shift lock key, a tab stop set key, a back spacer key, and a space bar. Behind each of the number keys is a bar which leads up to the adding attachment. Keys in a row across the bottom front set the place of the first digit in a number. The typewriter has two carriages. The front one carries a single register that indicates seven-digit totals. The carriage in back has tab-setting devices. Behind this is the ribbon, the rubber platen, and the paper tray. The machine has four rubber feet and two rubber handles for the platen.
A mark on the paper tray reads: Remington (/)Adding and Subtracting (/) Typewriter. A mark at the bottom front reads: Remington Standard Typewriter No. 11. Marks on the adding mechanism below the front carriage and on the moveable register read: WAHL ADDING MACHINE Co. (/) CHICAGO. The adding mechanism is also marked: PATENTED IN (/) UNITED STATES AND (/) FOREIGN COUNTRIES. (/) DATES & NUMBERS ON (/) BACK COVER. OTHER (/) PATENTS PENDING. (/) DISCOUNT. Marks on the back of the adding attachment give American, French and British patents.
