Curta Model2

There are three major variations of the Type II : black body, grey body, and grey body with plastic crank and plastic clearing lever.

The black body Type II looks more like the Type I because the main body is all black. All black body Type II's came with a metal crank and metal clearing lever.

In the late 1950s, Contina started producing the Type II with a grey crackle painted body and collar. These Curtas continued to have metal cranks and metal clearing levers. Then, in the mid 1960s, as with the Type I model , the gray Type II were supplied with plastic cranks and plastic clearing levers.

Black body Type II's came with a metal carrying case. The grey body models initially had metal cases, too, but a plastic case became standard in the early 1960s. Additionally, a LeatherCase was produced and was available as an accessory.

The factory phased in such changes (both the major version changes and minor component changes) over time. As a result, there are many "halfway" model variations. It is these units that often spark extreme interest in collectors. There were even a few Curta Type IIs made with a chrome plated crank and chrome edged clearing plate.
