Unknown The Signals Museum - RAF Henlow. Other CV1054 exhibits

The CV1054 is a pair of signal diodes in a single envelope. Each section is internally screened. When in commercial guise it is the EB34.

The red screening paint suggests Mullard. The KB/A indicates a UK specification and the A identifies the maker as Mullard.

The Reverse carries the remains of a stamped message.

With some enhancement the main lettering is still unclear. The final word looks to be serviceable.

The wide glass envelope is 29 mm in diameter and, excluding the IO base pins, is 66 mm tall.
