Olivetti Underwood Electrosumma 22 Adding Machine Antique Vtg Calculator

Description

Olivetti-Underwood Electrosumma 22 Adding Machine.
Cosmetically, there are a few scrapes and scuffs but nothing cracked or significantly structurally damaged.
No missing keytops. No cracks in the viewing panel.
When depressing the keys and pulling the crank the machine will tally.
All the keys worked until I pressed the red minus key which jammed. Release it and it'll work well.
Very Condition Overall.
