| 'This 1908 machine was
produced by "The Lightning Adding Machine Co." (Los Angeles, USA). The stylus
was inserted in the dials and turned clock wise for addition. This particular model,
though elegant in it's appearance, lacks the zeroing mechanism and the ability to subtract
which were common features in this type of machine.' Erez Kaplan. "Calculating Machines." |
