Data From Some Inspected Bulbs

This list is organised by bulb or container markings if bulb unmarked. Many lamps were made unmarked but the Incandescent Lamp Central Sales Office, in Berlin and many others around Europe supplied all of Europe and many would be supplied etched to order. They were manufactured by many companies. This list is a typical cross selection of lamps from the period up to 1950, but mostly from 1910’s to 1930’s.
