This calculator was manufactured by Marchant Calculating Co. in Oakland California USA. Patented in USA on Dec 4 1923. It appears that every part on the inside is original. The 1st column lever does not move up and down freely like the rest, see picture. It still functions but it is not smooth. I have had it on display and it's a great conversation piece. What you see in the pictures is what you get.
