[ARC5] BC-454-B Dymamotor Question

[Scott Johnson]

I would have assumed most of the "techs" were none too savvy in that era.
Ball bearings in general would have been quite novel in those days, and even
now, most people don't know how to handle, install, clean, lubricate, or
pre-load them properly.  Radio specialists during the great war were
processed through signal corps school in a not too effective fashion, and
even if they did retain most of what they were taught, they had precious
little experience when they hit their duty station, and not too much time to
hone those skill afterward.  They probably did the best they could by
swapping parts.  I would assume the "tough dog" problems were relegated to
the junk pile.  The great logistics monster that was created during WWII
eventually made deep troubleshooting and repair unnecessary (Witness the
huge amount of surplus now in our hands that causes us to ponder these
things now, some seventy years on.

Well, I had thought of that too, but I figured that not every radio tech in
those days was a dolt. ;-)
