Enigma ''model B'' was introduced late in 1924, and was of a similar construction.<ref>{{cite web|url=http://www.armyradio.com/publish/Articles/The_Enigma_Code_Breach/Pictures/enigma_type_b.jpg|title=image of Enigma Type B|url-status=dead|archive-url=https://web.archive.org/web/20051021083422/http://www.armyradio.com/publish/Articles/The_Enigma_Code_Breach/Pictures/enigma_type_b.jpg|archive-date=21 October 2005}}</ref> While bearing the Enigma name, both models ''A'' and ''B'' were quite unlike later versions: They differed in physical size and shape, but also cryptographically, in that they lacked the reflector. This model of Enigma machine was referred to as the Glowlamp Enigma or ''Glühlampenmaschine'' since it produced its output on a lamp panel rather than paper. This method of output was much more reliable and cost effective. Hence this machine was 1/8th the price of its predecessor.<ref name="Enigma History"/>
