        I was hoping that someone might be able to recommend any books, 
articles,
monographs, or other reference materials concerning the history and makers
of 17th and 18th century American Colonial sundials - particularly
horizontal garden dials. Also, are there any dealers who specialize in
these particular items and is there a reference which would indicate
current prices/values?

        Thanks very much in advance.

Sincerely,

Bob Shapiro
