Thank you, Ken -

The look of the sextant was what attracted my eye, I rather hoped it
might be a step up from the vernier Davis. I sent several questions to
the seller which were answered promptly and in a forthright manner. In
essence, the seller didn't know much.

I looked on the Internet but could find nothing about Yoder
Instruments, E. Palestine, OH.

From studying the photos I had a sense that it's underlying machining
was probably a bit rough. I particularly wondered about the
thumb-screw lock; suspected it might chew up the bottom of the arc. No
photo showed the underside of the arc, but it did look like there was
abrasion along the lower edge of the arc.

The fact that the vernier was marked in degrees, not minutes made me
suspect that the person who made it was not knowledgeable about
sextants. Ergo, my judgement was it wasn't a workaday sextant.

Net of everything, I decided it wasn't worth the asking price. The
sextant was not open for bids, just "Buy it Now for $145."

What you've said, confirms my sense of it, so....

Thanks again.  Hewitt
