Another author/artist. Note that in the picture above he's called Lawrence Bagley in error.
Laurence Cyril Bagley contributed to Swift Annual 5, 8 and 9, the last two cover dated 1962 and 1963, the latter supplied with credits to each of the stories and features which makes identification a whole lot easier. Also contributed to Girl Annual and probably elsewhere.
Bagley would appear to have specialised in maritime and aviation subjects and I've noticed one or two pieces of original artwork (such as the example below) coming up for sale. Other than that, there's a distinct lack of biographical information on him.
