Rare Soviet A-201 Dekatron Spinning

This is a rare A-201 dekatron from the former Soviet Union. Made in 1978, this tube is still in perfect working order today. I connected it to a spinner circuit and it runs fine in both directions. These tubes are interesting in that the glow transfer occurs on the center of the cathodes, rather than the tips. The lack of a shade ring or any other silvering of the glass makes these visually stunning. As always, the odd flicker is due to the shutter speed of my digital camera.
