    Re: Ebay Sextant?????????
    From: Joel Jacobs
    Date: 2004 Nov 10, 23:34 +0000
    Alex,
     
    Some good and valuable information. Thank you.
     
    I'm familar with the maurnavy site. I use it to check my prices on Russian equipment. In fact I have a polished aluminum version of the K-100 compass he shows at about the same price.
     
    From my vantage point, I would need someone to explain what the significant differences are bewteen the SNO-M, CO, CH, and CH-U. As far as I'm concerned they are all the same frame and index arm, and likely the same mirrors and optics. The index arm on all these are stamped metal. The addition of the magnifier or its ommission is not, IMO, a significant design variation to warrant a different designation. Note that one sextant has mirror frames that seem to have the same silver paint as on the SNO-T, a marbelized silver.
     
    I have sold SNO-M in both black and green paint. Or at least I considered them SNO-M.
