Vintage Stanley of London Fuller's calculator from the middle of the last century in its original mahogany presentation case with holding bracket.
This antique cylindrical logarithmic slide rule was invented in 1878 by George Fuller, Professor of Engineering at Queen's University Belfast, and despite its size and price, it remained on the market for nearly a century because it surpassed almost all other slide rules.
