I don't know whether you've seen this familysearch webpage./
It gives general information including an explanation of the three Polish areas on mainland Europe.
As others have also mentioned, the UK government only kept incoming passenger lists for ten years and then they were destroyed, although some were overlooked for varying reasons.
I've surfed to see if I can find anything, but unfortunately not. In case it helps and gives you an inkling; I found details of the arrival in England of my Hanoverian gt. grandfather in the County Police Files under the heading "Aliens" and there were only about a dozen Aliens in the file. He was 10 years, one day old when he arrived with some travelling musicians - and as somebody has already mentioned, there already were some other Hanoverian musicians from his home area, who were already in the English town.
