Fired up my GenRad 1217-B Pulse Generator, which is mostly tubes (I think there's transistors in there somewhere, haven't had it apart in a long time), and set the pulse width to 1 mS:

Automeasure on the Tek 2432A says 1.04 mS, not bad! Especially since 1 mS is the range select, and the actual width is set with a vernier dial! Unfortunately it's probably worth more for the tubes than as a pulse generator, nowadays.

Very nice! Sadly, you're right about the tube thing. I see a lot of vintage test gear at work and people do like to rob the tubes out of them, partly because they often used higher end brands like Mullard or Telefunken. The worst "offenders" are HV power supplies, as they often had 6L6s inside.
