Type 6BN6 is a late 1940s 'gated beam' valve in which the electron stream is deflected on and off of the anode. This 'chops' the amplified signal, typically at a very high rate.
The 'electron gun' is to the right of the picture above and the main picture is taken looking directly at the 'electron gun'.
See 6BN6 for more details and the second part of the data-sheet.
The thin glass tube envelope is 16 mm in diameter and excluding the B7G base pins it is 60 mm tall.
