[ARC5] Aligning BC-453-B. (Solved) Benefit from repairing a 'junker' (long)

[Bruce Long via ARC5]

i have a vague memory of something i read - perhaps here- that in American electronic equipment the transition from rubber-cotton insulted wire to plastic insulated wire occurred during WW2 encouraged to a large part by fungus rot induced equipment failures suffered by the first electronic equipment shipped to and used in the south pacific.

Tangential to the ongoing discussion, might someone tell me when the 
transition to plastic wire came about?  I find that these sets are 
infinitely easier to troubleshoot and trace issues and that components 
are (surprise...surprise...) relatively in-spec.  I find few resistors 
way out in "plastic wire" units that are found in good physical 
condition.  It may well be that its _all_ attributable to age.  Still, 
there is a clear transition....
