Unidad documental compuesta 1 - 'The action of crystal rectifiers'

Autograph ms., pages numbered 3-41, with a note by G.K. Batchelor, 'Found in G.I's garage in a water-stained folder, July 1976'.
Although the pagination begins p.3, the paper begins `Some months ago Sir J.J. Thomson suggested to me to try and find some explanation of the action of crystal rectifiers, and the experiments described in this paper are the results of this suggestion'. It seems therefore that the missing pages 1 and 2 did not include the substance of the paper.
Also included is correspondence re the paper between G.K. Batchelor and A.B. Pippard, 1976.
