So, yes it could be hand held but probably was more efficiently used as a desktop calculator. It’s 9 3/4″ x 4 3/4″ x 2″ and with it’s battery charger attached it’s just over 12″ long. It’s fairly large so I’m not sure it can really be classified as a hand held calculator though at that time in the early 70’s it was probably considered small. It’s the Olivetti Divisumma 18 and is the wild creation of Mario Bellini one of the creative designers at the company at the time. In fact, in 1972 when it was introduced by Olivetti, it WAS stylish. Wow, this is one strange looking calculator! Some might call it stylish.
