- The name of Lloyd’s Electronics does not appear on this calculator. However, the company filed for two trademarks for the term Monteverdi, used for other electronic equipment, in 1975 and 1976. These were registered in 1977. The calculator also is very similar in style to Lloyd’s model E419 (1986.0988.217).
