Hey Tim,

I don't know about 'fully' oriented, but according to Norton ~5% of
stony meteorites show 'some degree' of orientation, and that irons are
(helpfully!) 'sometimes' oriented. He attributes to Nininger an
estimate that 28% of irons are oriented, but doesn't define the degree
of orientation.
