British Korean War Miniature Medal Trio

Original era manufacture. Ok, now this is an interesting group we recently purchased in an Antique Mall here in AZ. British Korean War Service Medal on a WWII Ribbon??, General Service Medal with a Maylaya Bar and a Regular Army Long Service/Good Conduct Medal. Why the first medal was swapped out will remain a mystery for all time. At any rate, its a nice little set overall.
