Theshedman, I was in Barnstaple Market, Devon a couple of weeks ago, just browsing, when a medal caught my eye that, at first, I thought was something to do with HMS Glorious, as it had the pentagon-shaped ships badge, but it turned out to be from HMS Raleigh. Round the edge of the badge on one side, it said; "Part 1 Highest Individual Award". On the other side of the medal it was engraved on a centre block, surrounded by leaves, which said; "PCT EMERY D226535T D26"
I bought it for a fiver and gave it to a friend of mine called Emery. I don't know if there's a connection, and I don't know what the medal refers to. Perhaps you do?
