Magnesium is a very reactive metal and you would not want uncoated/untreated
magnesium esposed to the environment. Metal is NOT particularly
dimensionally stable, most metals expand and contract much more that a
properly engineered "plastic" component. The plastic component also has
much better thermal transmission properties. What do you think those "super
modern polymers are? Plastics....

It was one of a hand assembled pre-production run. Everything I
tried seemed to work. I would think the the full production
camera would be mechanically the same, but there may well be
some software tweaking before it hits the streets.
The plasticy stuff could well be a coating on metal. Actually I
hope not, the film plane, mirror box, ground glass, and lens
mount need the
dimensional stability and rigidity of metal. The outside that
gets kicked around by the environment is better off if made from
tough modern super polymers. I mean if it is good enough for a
hockey puck <grin>.
Addendum: The spec sheet does say the top and bottom covers are
die cast magnesium, so it must be a powder coat type finish.

Basically, that I had hallucinated the one I thought I had once
held in my hands. In other words he could find no reference to
it.
