I am planning on buying my first curta, and I would like a type 1.
I have heard that they had metal clearing rings and winding levers on the early ones, but when exactly (what serial no.) did they switch? I see some with the domed top winding lever, does that mean it is metal? how do you tell which ones have metal clearing rings? |
