I have three THALES - Odhner-type adding machines - for sale. I bought them in 1983 when the Librairie Canadienne in Quebec City, the exclusive Canadian distributor, went out of business after 100 years of selling everything from rosary beads to church vestments and slide rules.
Two of these (one black, one green) work well. The third does not work but I bought it for parts because it is identical to the green one.
They look exactly like the one at CALCULATING MACHINES ( http://www.webcom.com/calc/ )
