Vintage Olivetti Summa Prima 20 Manual Adding Machine Argentina WORKS

I am not an expert on this item and am judging that it's an Olivetti Summa Prima 20 by comparing it to photos of others. The calculator has been tested : all number keys and function buttons depress normally, the crank turns smoothly, and numbers do print.
