The picture of the top is of the tape readers for the Harvard Mark I, from 1944.
It's Peak Tabulating Machine, a reasonably general purpose automatic computer built from IBM tabulating machine parts. The project started in 1939, but was held up by WWII.
IBM's early computing history was a long struggle between what people wanted to do and what could cost-effectively be built.
