Oh, this was really common in Soviet radio, military and especially aircraft and space industries. Best part: Russian military stockpiled so much of amazingly durable PTFE-insulated cable that I could get miles of it for (relatively) cheap. Think anything from 36AWG to 12AWG. And yes, I often use the leftovers of 26AWG for my projects. That thing was something my EU friends were envying endlessly :) Sadly, with the EU RoHS regulations, I can no longer use this beautiful eutectic leaded solder... well, I can and do for personal use, but technically this is illegal :).
