The corresponding JRNL was published in 1974:

P.S. I knew there had to be some advantage to getting older.

Coming back to more recent times, I believe that the longest file in the PDB (including ribosome structures and NMR structures) is still 1HTQ at 985,553 lines. This contains a 10-model crystallographic refinement of glutamine synthetase.

Presumably this came out of the work described in the reference that Bart cited:

Highly constrained multiple-copy refinement of protein crystal structures
Matteo Pellegrini 1, Niels Gr?nbech-Jensen 1 2, Jennifer A. Kelly 1,
Gaston M.U. Pfluegl 1, Todd O. Yeates 1 *

which is Proteins. 1997 Dec;29(4):426-32
