Celestaire's AstraIIIB Deluxe is a modified Chinese GLH130-40, the AstraIII Professional a modified GLH130-20 (the main modification being a square instead of a round index mirror). On alibaba and ecrater, I have now come across what seems to be a third version of the Chinese sextant, desginated GLH130-60, with a slightly different index arm and micrometer drum assembly, a different scope, four horizon shades instead of three, and a "KTLASS" sticker (whatever that means). See included pictures. The alibaba one is pictured in a watertight box, the ecrater one in a wooden box with a certificate and manual of "Factory No. 701 of the Chinese People's Liberation Army's Navy." With the GLH130-40 and -20, the last two digits seem to point to specified accuracy in seconds, but it is not clear whether "-60" in this model similarly indicates a (somewhat lower) accuracy. I don't expect anybody here will have any further information on this sextant version, but maybe some of you will be interested.
