Kodak Duaflex (UK)
The original Duaflex was introduced in 1947, and was manufactured both in America and in England. The U.S. & U.K. versions differed in appearance, and I've always been partial to the British version.
Unfortunately, there doesn't seem to be any "camerosity" code inside this one, so I can't date it precisely. Nonetheless, I am happy to add it to my collection!
