Ditto what John says about Robert Mellichamp’s books on the 37mm and 1pdrs. If I remember right, the 1.457" is in the first volume. Also, pictures can be viewed at this link:

Gordon Spragge has a superb collection and has posted pix of most of the ones that can be found, including the 1.457" subcals. Gordon shows the two variants of the smoke shells with the 37x145Rmm casing. Robert’s book documents that casing and a much shorter casing and goes into detail. To view the link, you have to be a member, though, but the process is not hard at all.
