Jeff is right -- and this really strikes me as odd (well, not that Jeff
is right -- that happens -- but that the serial numbers are as they
are). It kinda defeats the whole purpose of having serial numbers in
the first place ;)
Here's a question: anyone knows if there're duplicate serial numbers?
I.e. if "they" started with a new low number when redoing the design,
and then "caught up" with numbers already used?
Not that it matters much, but it's a piece of OM-trivia which I think
we've not yet discussed to death ;)
