EXCEPTIONAL COILED-TUBE BINOCULARS, French, c. 1880. These ingenious binoculars are constructed with two gilt-brass main plates supporting not only the 2″ (5 cm) diameter objective lens cells, but also the complex assembly of axle with twin pinion gears engaging the long folding rack-works which drive a thick plate carrying the eyelenses, meanwhile extending the helical coils to form opaque tubes to exclude off-axis light. Materials include gilt brass, steel, horn, and shell. Condition is very fine noting a little nibbling to the organics and a little chipping to the enamel. This attractive and ingenious device extends from a compact 1-1/2″ thick to 5″ fully open (4 to 13 cm), and is complete with its original somewhat worn shaped case bound in blackened leather and lined in pink silk.
