Check the listing for details. Vintage Bullseye Bench Condenser Microscope Accessory Scientific Optical #26070. Made in United Kingdom. Listed at 104.49 USD. This brass Bullseye bench condenser is in "as found" condition. It is a little more unusual than most as it has a single arm on a ball joint. There are no chips or splits to the brass, however, there is some tarnishing in places and the usual scuffs and marks that you expect from a well used item of this age. The inner shaft moves up and down the outer sleeve well and it stays in place as it should. The ball joint holding the lens moves as it should and it holds the lens and shaft in place. There are no chips or cracks to the planoconvex lens. It measures 21.5 cm (8 1/2 inches) tall when extended and the base measures 6 cm (2 1/4 inches) across. Please be aware that customs or import duties may apply.
