This is an electrostatic deflection CRT suitable for symmetrical deflection. It is specified as having either a BYL10, BYM25 or BYL46 screen which will be blue flash and yellow afterglow with a medium or long persistence.
The CRT is supplied with a magnetic shield - this is crimped in place and cannot be removed.
With the base spigot upwards, when viewing the screen a positive voltage on X1 will deflect the beam to the right, and a positive voltage on Y1 will deflect it downwards.
