(200 words excerpt, click title or image to see full post)

A rare early financial computing device has been unearthed
among the archives of the Armagh Observatory by Thirza
Mulder, Archivist for the Armagh Public Library. The British
Calculator, Model C, was part of the personal collection of
Joseph Alfred Hardcastle, who had been appointed Director of
the Observatory in 1916 but was taken ill and sadly died on his
way to take up residence in Armagh. The item, which appears to
be for use in the addition of pounds, shillings and pence, formed
part of the Hardcastle material auctioned by the firm of George
Mealy and Sons Ltd. in December 2003.
