    Hadley Quadrant - Gilbert - Tower on the Hill - 1771
    From: Jim Rives

    I recently was given what I believe is a Hadley Quadrant.  The (damaged) nameplate indicates that it was made by a maker who's last name was Gilbert (Thomas?) on Tower Hill, London, in March 1771.  I cannot decipher the name lower on the nameplate, which I guess might be the retailer or the new owner for which it was built.  

    As a kid, when we visited Newport, I was always fascinated by that quadrant hanging on my grandfather's wall.  The damaged index scale and nameplate had happened before the 1960's... rumored to have been gnawed on by the family dalmation.  If so, they must have fallen off onto the ground as there is no sign of any force appied to the frame of the quadrant itself.  Still, it is unfortunate.  

    I believe this may have come from a ship chandlery in Newport, RI.  I am beginning to research these instrumets, and have searched the web, NavList and Mr. Morris's website.  The latter are especially helpful, and I can see I have some homework to do.  But I thought I'd post a few pictures of the one I have to see if anyone has any advice or suggestions on research material to seek out.  

    Ultimately I am interested in having an appropriate institution acquire and care for it.  I'm pretty sure it has little monetary value but it has survived 250 years so far and deserves a good home somewhere someday.  

    Thanks in advance for any comments or suggestions..
