Thanks Frank.

As long as we are posting e-bay listings of interest, the list might want to
check this C.Plath out. A very good deal and a rare item comes with it: a
Plath Bubble attachment.  The attachment alone is worth the $800 for the
opening bid.

But hurry: the bid ends in one hour.

Now check this item out:

This is for a C.Plath yachtsman. I have never seen the like of this before
and I have two books on C.Plath sextants. Would appreciate it if anyone
could fill me in on the details of this little gem.  It looks like a
lifeboat sextant.
