Description

Vintage Olivetti Underwood Summa Quanta 20 Adding Machine W/ Cord. This is used and needs the ink ribbon. This sold as is for parts or repairs, all the buttons seem to work but it does not do the math. I dont know anything about these so it may be an easy fix or I may not know what I'm doing. This has the original power cord and comes with the paper roll that is currently on it.
