Finally, I have found a newspaper cutting which announced the introduction of this badge. Please see below.

A word of warning. Whilst I have been seeking information on this badge I have seen many illustrations of what were claimed to be the Mercantile Marine Torpedo Badges in gold wire, several with the star above. To me the ones with the star above look just like the trade badges I referred to earlier - and the ones without the stars look just like the torpedo badge issued to ratings without any letters or stars (such things were often issued separately). I would certainly be very careful about buying gold wire examples of this badge without something to confirm it's history.
