Does anybody know of a portrait of Stephen Butterworth (1885 - 1958), a British physicist?

Here is a picture. The page is taken from Chapter 2, "Frequency Domain Analysis" in Dennis Silage, "Analog and Digital Communications." Where did Silage find the photograph I do not know, you can email him and ask.

This picture is not Stephen Butterworth (inventor of the Butterworth filter) to whom the text refers. Stephen Butterworth was my grandfather and this is definitely not him!
