Thanks Martin,
The market, at least on eBay, seems to agree with you that there are few differences. There are no cheap GLH- sextants any more. Almost all seem to be described as Astra’s or Astra/GLH- and are all over $400.
I looked at 21 examples for sale, or sold, trying unsuccessfully to spot any consistent differences.
The company names on the papers have lots of variations of Celestaire, Changzhou, China, Marine, Haiyue, Instrument, Equipment, and Technology.
Serial numbers on the papers or on the sextant range from four digits to seven. There was a 1989 with a six digit SN and a 1998 with a four digit SN. All with dates after 2009 had seven digits.
Dates on the papers range from 1988 to 2017 - no significance there.
I was surprised to see two separate ads that had photos of two very different serial numbers on the sextants in the same ad.
Regards, Noell
