The CV9167 (ECL82) is described by Mullard as an audio triode plus output pentode. The Mullard name does not appear on the glass but the typeface is typical Mullard.
The triode section has a amplification factor of 70. Application would be audio stages and television receivers.
The triode can be seen to have copper grid supports.
The triode on the left. The hole in the anode shows the relative electrode spacings.
The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins the valve is 68 mm long.
References: Data-sheet & 1040. Type CV9167 was first introduced in 1956. See also 1956 adverts.
