Well here I was going by the definition of normal being equal to the
diagonal of the format.  There are probalby other definitions out there 
of which I am unaware.  Measuring an Albion 5-perf mask I have here in 
my drawer, I see the diagonal is 31.1 mm.  So by the defintion I cited, 
the lens on a Realist is probably normal.
