Incredible; looks brand-new. The unit I had was a dirty mess by comparison, which probably led to it being unreliable. But, mine had no tubes. Plenty of transistors, though.
When I was in high school, a local company donated several nixie+stepper voltmeters, and they were annoyingly noisy because the least-significant-digit was 'wobbling' all of the time. DMMs (with 7-segment LEDs) became relatively cheap and widely available then, which killed nixies.
