The photographer, Henry Bown, appears to have been operating in Deptford between 1906 and 1921 and Walworth 1906 to 1913.
I would be interested to know what is on the medal index card for the Frederick Codd, 29th Bn London Regiment. I know they were a Home Service unit, but there appears to be an affiliation with the Royal Fusiliers and their cap badge was the same, although obviously not a match in this photo.
