Nope--I remember them also. Plain dead-simple NE-2 type package.
The application I recall them being used in was as a trigger for a
touch-sensitive switch. (They may have been used in security
applications also). Coupling stray AC via one's body to the third
electrode was sufficient to cause the neon to fire. I've also seen
this kind of thing done with 2050 and 2D21 thyratrons also, but the
neon bulb would clearly have a power advantage.
