USER'S REPORT: Robert XXXX an experienced
celestial navigator has this to say about the Ilon sextant which is posted on a website devoted to the science of the topic.
best "box" sextant I come across was manufactured by Ilon Industries out of New York. My late friend John Luck owned
one, and for years, I tried, without success to get him to sell it to me. I have not since seen another example of this item,
but you can find a photo of one in Ifland's "Taking the Stars", on page 49, Fig 55.
I have been scanning e-bay every once in a while in search of an Ilon, but always come up with zilch. Could be that
very few were manufactured in the first place. I would dearly love to get my hands on one of these sextants. Robert XXXX"

We know Robert to be an experienced navigator and takes his sights mostly at sea rather
than from an armchair. We value his opinion. However we don't agree with him here. Many users will find this sextant
too small for comfort and our recommendation as to the Best Miniature, would be the British WW II Air Ministry sextant. See http://landandseacollection.com/id777.html

That said, if you are a collector or student
of celestial navigation, this interesting instrument will make a worthwhile addition to your collection, and also will add
immeasurably as a conversation piece.
PROVENANCE: None known
INSTRUMENT CONDITION: The very well made sextant is in excellent condition considering its age and use. The
handle attaches though a hole in the frame and the paint has been scratched off by its rotation. This is very minor.
There are some tiny spots on both of the mirrors. They do not interfere with taking sights. The tube shown in the photos is
a sighting tube with no optics. Most small sextants have low powered telescopes so this may be satisfactory.
The index arm is complete and in good working order. The frame and all the machinery are in good working
order. It comes with its original adjustment wrench for the mirrors. All the screws and fittings show their original gun
metal bluing and the slots are sharp.
The real leather case is generally in excellent condition with just a few small areas of loss. The interior velvet lining
has some stains. The stitching is tight and the zipper works. There is one empty pocket in the case.
