Well, I have certainly seen the odd medal to Widgeon, but, I think she was just a Gunboat, they will be scarce, there are certainly photographs of her moored up at Simons Town during the war, but, I can't remember the last time I saw one to Beagle, I suppose it is really the sort of thing you have to buy at the moment you actually see one, which might be very soon, or, indeed, some way off.
Good luck, I am sure they will turn up in due course.
