SI-19BG tube disappointment

Earlier today I connected the tiny SI-19BG tube to the test circuit. Unfortunately, not one single count was registered. 

I obtained this tube from eBay seller "2015_gurie", and am now in contact  with the seller concerning a replacement tube.

It might be that I've just been unlucky and received a failed unit, or it might be an error in operation due to the lack of good information on these tubes.

I will transfer it to my variable HV supply and probe the tube with the scope, to see if there is any activity at all.

I've just today ordered a new, modern scope as well!
