charliegolf, I have tried to reply to your query about a lost medal, but your inbox is full. I might as well post it on here as it may well be of interest to others.
The address to write to when requesting a replacement for a lost/stolen medal is
MOD Medal office
Innsworth House
Imjin Barracks
Innsworth
Gloucester
GL3 1HW
This is the address for all medal queries, including initial claims. Some years ago I made a successful claim for a medal which my late father had never been issued with, but they will not replace claims for lost family medals once the recipient is deceased. It's worth pointing out that the service is not free, and the sums involved are not trivial, over £50 for a replacement GSM as I recall, although of course there is no charge for an initial issue.
