Smaller CRTs

This is the smallest CRT I have. It's a magnetic deflection tube from a camcorder viewfinder. Its about 3/4 inch diameter.

This Cossor 1CP1 is British made. They also made radios.

These type 902 2 inch CRTs (above) were very popular in home brew scopes, along with the 2AP1 and the 2BP1 (below):

This 3HP7 tube has a long-persistence phosphor.

I'll admit that I'm too lazy to get the type numbers listed here. Yet.
