It was apparently written at Berkeley under the direction of Le Cam, and it is cited in a number of contributions to mathematical statistics, for example in Strasser's (1985) book "Mathematical Theory of Statistics". There Strasser states on page 130 that he follows Moussatat's proofs (of a theorem of Wald). Since I don't understand Strasser's proof on pages 131-132, I would like to have a look at the original, but could not find it anywhere so far. Any help would be greatly appreciated.
