 "Tips concerning those big 1930s PL-series connectors
like the PL-61 and PL-64:

First- the Bakelite inserts absorb water and swell.
Some have swollen enough to split the metal 
outer shell."
The plugs were apparently manufactured to have a 
tight fit - they were that way in 1948 also.
"Second-  Those infernal locking clips, 
with the two short locking pins on them."  


I got tired of trying to deal with them using a small
 screwdriver thru the back port of the plug.  I got an
 old steak knife at the local thrift store and ground
 the blade down to about the dimensions that you
describe. It's a great improvement.
