Left: What appears to be a Type 012 Electric Duplicating Key Punch in the
Crystallography Lab at the California Institute of Technology. The only
puzzle is it seems to be handling 80-column cards with rectangular holes
which were introduced in 1928, whereas the 012 pictured above uses 45-column
round-hole cards. In any case, it appears that this punch was procured for
the lab through a request from
Pauling to IBM's Director of Pure Science,
Columbia's Wallace Eckert in 1947.
