A medal that has been on display in Orkney's Stromness Museum for years has been identified as one awarded posthumously to Sir John Franklin.

Military historian and medal collector Hiram Dunn spotted the medal on a visit to Stromness. But when the museum told him it had been donated by Rosalind Rawnsely, he realised there could be a direct family link to Sir John Franklin. He said, "nobody ever knew where Franklin's Arctic Medal was".

Jeremy Mitchell from the National Maritime Museum at Greenwich said it was appropriate that Franklin's medal had ended up in Orkney. "People forget that Stromness was (Franklin)'s last landfall, and the expedition spent three days here before disappearing off to the Arctic."
