Found this little box with a small tube among my tube collection.
Made by Rogers in Canada. The unusual part is the note that was enclosed asking hams for suggestions for using the tube, I guess after the war there was little use for this.

You could win $5.-!!!!

I have some of those! I suppose that you can make them into a necklace or earrings. You can also buy a cheap neon tube tester off of Greedbay and make them light up. :lol: :lol: :lol:

What is the breakdown voltage? How about long wire antenna lightning arrestor?

From Rmorg:

Gas filled spark gap. Tungsten tipped electrodes, ceramic sheat over the zone of discharge. 0.4 mm gap. The device was filled with argon and a small amount of mercury. 100 us recovery time. 650V max striking voltage. Several hundred hours useful life at 25KW.

A friend in Canada beat you to it. He collects Rogers stuff.

Check it for radioactivity.
There were some T/R tubes with radioactive gas to protect the mixer diode from the main bang by firing more quickly.
I do not have information on this particular tube.
