CD27
54 mm numeric tube manufactured by Rodan
The CD27 is a clear glass numeric nixie tube manufactured by Rodan. This tube is counting to the largest nixies ever made, especially end-view types and is very rare nowadays. The black base enclosure gives the digits a very nice and warm shine!

Equivalent tubes are either the exact same type made by a different manufacturer, or models that differ only very slightly from this version (e.g. red coating instead of clear glass).
Similar tubes share electrical and mechanical specifications with this tube, but are not exact replicas.
Note
The tube glass is a bit shaded from heavy usage so i added a long-exposure photograph to give an idea how it would look in new condition. Very beautiful tube
