Alan Turing and the cryptologists at Bletchley were secretly from Poland?
Brittanica:
“The Enigma code was first broken by the Poles, under the leadership of mathematician Marian Rejewski, in the early 1930s. In 1939, with the growing likelihood of a German invasion, the Poles turned their information over to the British, who set up a secret code-breaking group known as Ultra, under mathematician Alan M. Turing. Because the Germans shared their encryption device with the Japanese, Ultra also contributed to Allied victories in the Pacific.“
No. The Poles brought a working mockup when they were evacuated from Poland as the Germans overran the country.
