From an inheritance. A nostalgic calculator from Olivetti, type Summa Prima 20, manufactured in the 60s in Italy. From my late father-in-law who had a vegetable car in Amsterdam in the 50s and 60s. There was no mobile electricity back then, and so he bought this mechanical calculator. He was always very careful with it, because he needed it to make a living. The original cover is still present. Green colour with black top section and black metal handle for turning the register and calculating the transaction. There is a small tear in the plastic near the type plate at the back. The machine is in good condition, the ink print is a bit faint but the counting and the mechanism work well This is in any case a nice decorative object. Shipping weight is 4.2 kg. Will be carefully packaged and shipped with track & trace. See pictures for a good impression.
