Curta Type II Calculating Machine Math Grenade
A great Curta Type II calculator or calculating machine, with its serial number of 558182 dating it to June 1970, with container and instructions. Offered in very good condition, having passed the TGB test, with hardly any signs of use. The price includes insured postage within the UK.
Curt Herzstark originally worked on the design for the Type I in his homeland of Austria in the late 1930’s but with Jewish heritage was incarcerated in Buchenwald Concentration Camp during the war, and forced to work on the design there, supposedly as the authorities wished to give the first as a gift to the Fuhrer as a victory gift at the end of the war. After WWII, Herzstark relocated from Weimar to Western Germany and from there moved to Liechtenstein, where production started in 1947, finishing in November 1970, although sales continued until 1973. There were two versions produced, the Type I, of which approximately 80,000 were produced, and the slightly larger Type II, of which approximately 60,000 were produced. The Type I has 8 sliders for data entry, a 6 digit revolution counter and an 11 digit result counter. The Type II has 11 sliders for data entry, a 8 digit revolution counter and a 15 digit result counter. Their similarity in shape to a hand grenade gained them the nickname of the “Math Grenade”. Please also see the Curta I I have for sale, also owned by the same person, which dates to September 1966.
