Subject: [Rasch] Paper by D Lawley

Rasch colleagues,

I would like to locate a paper by D Lawley published in the early 1940s. It was
in this paper that he recognised the (b-d) parameter as a requirement for
measurement and that it must be normally distributed.
Does anyone have a reference for this paper - or even a copy?
