    I forgot to note that a Mann Measuring Engine, similar to the one
mentioned in the Ap.J paper for measuring photographic plates sold on eBay a
few years ago at a fraction of its original cost.  It was in the south
eastern U.S.  I was going to bid on it but was scared off by shipping costs
as this thing is heavy.  If you do a search for "Mann Measuring Engine" with
google you can see photographs and descriptions of some of these
instruments.  I'm now sorry I didn't bid on it.  Never seen anything like it
since!
    I wonder if anyone knows where this unit ended up and what it is being
used for, if anything?  I think it was U.S. government surplus, perhaps from
the US Naval Observatory but I don't know for sure.
