- Description
- This stylus-operated steel notched band adder has seven crook-shaped columns and one straight one, with eight notched bands below. Eight windows show results, and a narrow clearing lever is at the top. A steel plate slides over seven columns in the shape of inverted crooks, as well as an eighth straight column. These are used in subtraction. Instructions accompany the instrument. Compare to MA.313629.
- The TASCO pocket arithmometer closely resembles an adder sold by the Gray Arithmometer Company of Ithaca, New York, in the early 20th century and distributed by the Morse Chain Company of Ithaca in the 1920s. In 1929, the Morse Chain Company became part of Borg-Warner Corporation. Distribution of the adder soon shifted to the Tavella Sales Company of New York City.
