Lee,

I compliment you on your honesty, and thank you for your help. I now have
the file and can manipulate it.

Getting back to maintenance, I still have the MS 733 Spica that was at sea
with me for eight years. The sextant is like new with no evidence of salt
corrosion except where some of the machine screws lost their plating. There
is no bubbling or lifting of the paint, blackening of the mirrors etc. And
all that time it lived in a salt atmosphere. The procedure I followed was
that which I recommend.

BTW, I also admire your choice of sailboat and place you live having been a
frequent visitor to Moorhead City and Beaufort.

Joel Jacobs
