Reid made Leica III and Leica Standard copies, but too late to have been useful during WW2. Just the same for Kardon, on the US side that time. These cameras were really copies, not Leica fakes as those we have here.
Just to complete what Steve said, two photos of my Reid "periscope":

And about the Fed 1b cover, I wonder if it's a real one. I have seen too many Leica fakes, with that type of cover, to be persuaded. Note that Leica used that type of round cover only in 1932 for their Leica II. In 1933, the Leica III appeared and used a "cornered" cover for the slow speed mechanism. We find that cornered cover from the Fed 1c-s...
