The CV1596 is a split beam double trace oscilloscope tube. Split beam tubes were introduced by Cossor Ltd. The electron gun is fairly conventional and produces a single electron beam up to the two vertical deflection plates. The splitter plate is normally connected to the first anode and two separate vertical deflection signals are applied to each individual vertical deflection plate and referenced to the common splitter plate, to produce two separate traces.
The CV1596 has a 4.0 Volt heater, which was common for tubes of its time, and required approximately 2 kV of EHT. The prototype was the VCR518A.
The bell with printed identification. The maximum diameter is 113 mm.
The pinch is on the right and the electrons pass to the left through the electron lens formed by the plates and voltages.
The 12 pin B12B base. The pins and spigot seem slightly different to B12B and so this could be a special base.

This image and the main picture have been taken in an alternate 'studio' with the Nikon DF camera.
The end window envelope is 49 mm in diameter, and excluding the B12B base pins is 350 mm tall.
