The Brimar 6K7 style of pentode was designed in the mid to late 1930s for intermediate frequency amplifiers in 'modern' superhet type receivers. It is high impedance allowing for a high Q in the tuned anode circuit.
See also the 6K7G full sized glass envelope version, and 6K7 original metal valve.
The outer cylinder is the screen. The anode cylinder is sited a couple of mm within the screen.
The wide glass tube envelope is 29 mm in diameter and excluding the IO base pins the valve is 72 mm long.
