PP, I believe you meant RD Jones (aka Four-fee Jones) Most Secret.
According to Winterbotham, a Pole was working on the coding machine in 1938 in east Germany. His security clearance was revoked and he returned to Poland and was subsequently smuggled out by the Polish Secret Service and set up in Paris with the help of the Deuxieme Bureau. He made a wooden mockup of the machine on which he had been working.
From the mockup we were able to identify it as an enigma and a new one was obtained with the help of the Polish Secret Service.
