Saw this tiny tube on eBay, and purchased it on a whim, as you do. Apparently a 4 volt heater. Can anyone identify the type?
I think I've answered my own question ..
VCR522?
Appears that VCR522 is equivalent to CV1522 and all information suggest it was made by GEC with commercial type designation E4103/B/4.
It might be worth checking these links:

Also have brief data for GEC E4103/B/4 if required.
This tube has a green screen type B which has 100ms persistence . Va1,a3 absolute maximum is 1kV

Was this the tube in the GEC Miniscope?
Now that magic eyes are increasingly rare and expensive, you could feed one set of plates with 50Hz to generate a line in one plane and the other set with AGC to deflect it ?

Indeed, GEC used their own 1 ½ " CRT an E-4103-B-4 as shown below, perhaps the tube Andy has here is an equivalent?

The data would suggest that. I'll see if I can get it to light at some point
