Hi Keith
These pics may be of some interest to you ;
After Dave had mentioned the Royal Fusiliers, I felt sure I had seen a similar badge (or medal) to your no 3 device among my records, and, after some searching, I came up with this rather surprising item.
The extracts are from the Journal of the UK OMRS, Spring 1990, and appears to show the same (or very similar) device being worn as a regimental medal, viz. the "Albuhera Cross" awarded to Clr Sgt Henry Parkinson, 7th Foot.
So it would seem that these devices were used in a variety of functions. Regards Jeff
