According the the OM-4 brochure I have "The Measure of the Professional"
the OM-4 was increased by 1mm to accomidate the seals. Hence the bottom
plate covers are 1mm more than OM-1's and 2's.

"Shower Resistant Sealings
   The reason the OM-4 is just a fraction larger than the OM-2 has
nothing to do with the Multi Spot Metering function, or with the many
other refinements incorporated in this new model. ... The extra millimeter
is taken up by a layer of shower resistant sealings that makes the OM-4
considerably more resistant to inclement weather."
