Record Model 1 Calculating Machine

This German key-set manually operated stepped drum calculating machine has nine columns of black plastic keys, with nine keys in each column. The rods between each row of keys, colored black on one side and white on the other, serve as decimal markers. The operating crank angles out of the right side at the front. A lever near it is marked Hand in one position and Automatisch in the other. Above the keyboard is a row of nine windows to indicate digits entered. On the left side is a lever. It is marked Subt.& Div. in one position and Add.&Mult. in the other.
In back is a carriage with two rows of windows. The front row holds eight digits and the back row 13. On the right side of the carriage, a zeroing knob is next to the first row, and a space for a zeroing knob is next to the second. At the back of the machine are thirteen metal columns. Nine of these have stepped drums on them. The drums are cutaway, somewhat like those on a TIM machine.
A mark to the right of the keyboard reads: Universal (/) Rechenmaschine (/) Record (/) Fabrikanten: H.Oehlmann & Co. (/) Berlin S.0.16. A mark on the front reads: Bureaumaschinen-Gesellschaft (/) Bernhard Behr & Co. (/) Dresden-A und Berlin S.0.16. At the back left under the top of the carriage is the mark: 434. A fourth mark, painted on a bar on the carriage, is:27-65. This is a number of the Museums of the Peaceful Arts in New York. This particular machine came from the collection of L. Leland Locke.
The Record was introduced in 1913 in Oldenburg, and the manufacturer moved to Berlin the following year.
