Description

This pair of binoculars, or opera glasses, have folding clamshell-like covers for the objective lenses.  The covers are trimmed in brown leather.  The objectives are positioned by turning a lever that rotates the lenses from a horizontal to vertical position.  This permits the glasses to be folded to a very compact size.  The objective lenses are achromatic doublets, contained in brass cells.  They have plated brass tubes, single lens eyepieces, and flared eyecups, painted black.  Focusing is done with a central cylindrical thumbwheel.  All the metal parts appear to be plated or painted brass.  They are signed "LEMAIRE FAB^T   PARIS" on the face of the eyecups.
