It is very obviously the Medallist I, thanks, they were never imported and sold here in the UK. It's likely been bought from someone in the US forces, directly or via a shop.
Cameras were in short supply here in WWII, I have 3 or 4 wartime Amateur Photographer magazines and there are adverts requesting cameras for the forces. After the end of WWII we had very strict austerity Import restrictions, you couldn't buy a camera from abroad without a special licence and that only eased in the 195os, but there was still a high Luxury Goods Import duty of 33%.
So Kodak Medalist cameras are extremely rare here in the UK, I've never seen one. Our Kodak cameras were mostly made in the Kodak Nagel plant in Germany which was a subsidiary of Kodak Ltd, although a few mostly LF were made here in the UK.
