The Curta Calculator (full documentary) Review / How To

Video Description

This is a super-edit of my "12 Days of Curtsmas" series, cut into a single episode. No new content here. I suppose this is episode 79 of my video series about old calculating devices. This is a Curta Type I, built in 1952. Eternal thanks to the person who gave me the Curta.
