Austin Adding Machine

Description
This adding machine has an iron frame with glass sides, back, and top. Across the front are ten plastic-covered keys. The operating crank is on the right side. The number entered appears in one window under the glass, and the total in another window. Decimal points and commas are represented by painted arrows. There is a zeroing lever on the left side. The machine does not print. The machine is marked: AUSTIN. It is also marked: Austin Adding Machine (/) Baltimore. U.S.A. A tag attached to the base on the inside of the machine toward the back is stamped with the serial number: A-1224.
The donor acquired this machine in the early 1960s from a veterinarian’s office, where it had remained after the doctor passed away in the early 1930s.
