Remington Rand 93 Adding Machine

Description
Like many religious organizations, Christ Congregational Church in Silver Spring, Maryland, used an adding machine to track its finances.
This ten-key printing electric adding machine has a black plastic case and a metal base. It has a block of nine white number keys with a 0 bar below. Subtract and repeat keys are to the right of the number keys, and a total bar is to the right of these. Left of the number keys are non-add and subtotal keys and a correction bar. A place indicator is above the keyboard and a printing mechanism, carriage, and motor behind it. A hinged door opens to give access to the black ribbon. Color-coded dots above the paper tape serve as place markers and a serrated edge assists in tearing the tape. The printing mechanism has room for further digit fonts. One may enter numbers of up to seven digits and print results of up to eight digits. A cord extends from the back of the machine. There are four rubber feet. When the machine prints, decimal points are not indicated.
The machine is marked above the keyboard: REMINGTON RAND. It is marked on the right side: MODEL NO 93 (/) ADDING BOOKKEEPING * CALCULATING MACHINES (/) MADE IN U.S.A. The serial number on the base is 93-710565.
