Hello all. I just came across two vintage original Leitz Leica cases. One has mounts to hold 3 M lenses and other little bits and pieces and the other seems to be just for a camera? I am no Leica person (MF)- so have no idea about these cases. I have tried searching here and there but can't seem to find any info. Any help identifying the model names- or exactly what equiptment these case are for- will be much appreciated... thanks in advance.
