WHO PUT THE NAMES ON BRITISH TRANSISTORS

The early 1950s to the late 60's were a period when many British manufacturers (there's a novelty....) made semiconductors.   Have you ever wondered how these minute curved surfaced items were indelibly marked?

Well, Rejafix made the printing machinery.  Rejafix, also known as Mark-O-Print was started by the Edels family in August 1947 and soldiered on until 1992.
