Doug, 
It is not unusual for components to age and drift.  As long as meter reading is +/- 10% (20% on carbon resistors) it is usually not a bad indication.  Expect that tubes could go bad and caps to short.  Pull tubes and check again.  Electrolytics are prone to aging as are old silver micas.

I managed to obtain some really nice braided fishing line and used that to
re-string the tx and rx dials.  It worked very well.

However, I just discovered a whole lot more problems.  While carrying out
the preliminary ohmeter checks, I found just over half of the checks turned
up incorrect values.  So, I've obviously got a lot greater issues to deal
with than dial string.

I think I'll put the project aside for a while and re-visit it at a later
date.
