Well, the details of the Leica IV are a bit hard to run down, though the
original survives in the Leica Museum.  My figures are that it had a 60mm
RF baseline and 0.9X magnification, for an effective baseline of 54mm.  The
early Contax I, with its effective baseline of 92.7mm, still takes the
honours as the longest 35mm RF baseline.
