The German Triumph company was founded already in 1896 as a daughter company of the UK Triumph Cycle Company and manufactured bicycles. In 1913 the company split and started to manufacture office equipment, e.g. typewriters. After a merger in 1958 with Adler the Triumph-Adler company was the 5th largest manufacturer of office products and was sold end of the 60s to Litton.

This SOLAR MINI was manufactured in 1979 by Towa Sankiden of Japan and and is one of the earliest calculators using solar cells instead of batteries. Don't miss the TEAL Photon and Towa Sankiden V-001.
