Thank you for the welcome; I had always believed that mine was the "Billy" but had never seen photos of that model which looked the same as mine and a couple of years ago a photographer friend suggested that it was a "Compur", which is the make of lens fitted.

It certainly uses 127 film...only one roll of EFKE left :-( ...I shall upload a photograph of it and ask for thoughts.

Whatever it is called I should now be able to produce some film to use which is something to look forward to; the lens creates the most wonderfully soft images.
