Having spent almost 7 years at National Radio I am still amazed at what
was used to wind coils, chokes, etc.
They had rows of mechanical nightmares that could do some strange things
with wire, including winding high power RF chokes from multiple spools of
Litz wire.
This was all before the days of computer driven manufacturing and some of
the gear dated from the 1930's...yet it ran at sometimes 2 shifts a day
and never broke down that I can remember.
