    Re: eBay item 7302517075 (Ends Feb-27-05 13:01:56 PST) - Sextant Simex Mariner Japanese
    From: Fred Hebard

    It's not a Jupiter, and I'm not sure that it was made by Tamaya.  There
    were several other manufacturers of sextants in Japan.
    
    Did you see the Spica with 2 scopes that just went for $810?  It looked
    to be in mint condition.
