Shown are some of the people (mostly women my dad told me) putting together the wiring for the B-29 Bomber. Dad was in charge of the electrical wiring that was done in Detroit. He would visit the assembly lines often.
Two things I remember him telling me about the electrical wiring. One was it was mostly women doing the work at Hudson Motors of which my dad was a chief engineer & two the wiring was connected by crimping much the same as is done today by most of us shade tree mechanics when we wire our car trailers or work on the electrical wiring of our cars, boats & recreational vehicles.
