This Mullard metal valve is marked Amerty - a term used by Mullard for valves that they imported from the USA in the early 1940's. This was probably made by RCA and for the large order the Mullard red paint was sprayed onto the metal can.
Type 6C5 disappeared from the lists fairly early because the design was superseded by the 6J5 which had slightly superior ratings and characteristics but was, for all practical purposes, a direct replacement.
Most 6C5s were of the metal-envelope type whereas most 6J5s were 'GT/G' and therefore suitable for a wider range of applications. NB. Type 6SN7GT is two independent 6J5s in one envelope.
The reverse just carries the Made in USA lettering.
The thin metal tube envelope is 25 mm in diameter and, excluding the IO base pins, is 50 mm tall.
