Austria Calculator -
1905

"Samuel Jakob Herzstark was born in 1867, he studied
mechanical engineering, but had to stop because of the death of his
father. He worked as a salesman in the textile business. His love of
machines made him to work on the development of office machines. After
several years in this field, he founded the calculator factory "Austria"
Herzstark & Co, Vienna. He improved the Thomas-system and started the
production of his own stepped-drum calculator.

There were several models. Model III had 6
digits in the setting register, 12 in the result register and 7 in the
counting register. Model IV had 7 digits in the setting register, 12 in
the result register and 7 in the counting register. It had a locking
mechanism for the crank (against operating errors) and a mechanism to
shift the carriage by pressing a key. Model V was made with 7 (9) digits
in the setting register, 14 (18) in the result register and 7 (9) in the
counting register. Model V could be provided with an electrical
motor."
