But I think the fact that the base plates are not original DOES explain the
apparent gap in the numbering sequence. I suggest that the camera with
serial 425981 in your list does not have its original base plate - it has
the base plate from an older camera. Olympus did not have the same approach
as a famous German camera maker, who always preserves the original serial
number even if the camera is rebuilt - the serial number is tied only to the
base plate. Switch the base plates around between two cameras and the link
between the serial number and the manufacturing code is broken.

Thanks Piers,
Even if the base plates are not the original ones, that doesn't explain the
drop in the serial number. To me it looks as if some [or all] factories
first continued numbering through from one model to another and after a
while added a 1 before it, which may explain the numbering of the OM1MDs
from the 'H' factory, because you can't imagine them producing more than 1
million bodies in one month and the next month maybe a few hundreds.
