Vintage Olivetti Summa Quanta Electric Adding Machine Mid Century AS IS

For your consideration is this cool vintage Olivetti Summa Quanta electronic adding machine/calculator circa 1940s-1950s. 

It turns on and a couple times I got some of the gears to engage but since then it seems stuck and nothing engages and I can not get any buttons to depress and work. So I don't know if an electronics wizard can get it in working order or if it's just now a cool prop/object d'art/ or parts machine. So you are buying it as is!

It measures about 13” long x 7.5” wide x 5.25” high and will weigh about 11-12 lbs packed safely. Thank you!
