Calculators Marketed by
Sumlock Bondain

 

... Sumlock-Bondain, a company with its roots in the Sumlock-Anita calculator business.  It was formed by people made redundant by the takeover of Sumlock-Anita by the U.S. giant Rockwell, who did not want to see their talents go to waste and decided to continue in that same business.
    Originally they sold the Sumlock calculator range but when that was wound up by Rockwell, they found favour with Texas Instruments, for whom they are wholesalers, and with Hewlett-Packard, for whom they act as a main agent.

Sumlock Bondain marketed at least one desktop calculator, as shown below, which could be considered the end of the line of Sumlock calculators.
