Caution! The evacuating horn on that tube David is very delicate. I do hope it has a bit more emission compared to your example. Being side pumped they usually stand a better chance. [Less cathode poisoning due to the 'dirty air' being extracted from the bulb rather than being dragged over the cathode via a pinch pump tube.]
Only a test will tell. Fingers crossed...John.
