A gorgeous pair of antique 19thc French Lemaire mother of pearl mechanical opera glasses with extending and detachable lorgnette handle. Panels of luminous white mother of pearl surround the handle and both binocular barrels. The focusing mechanism is truly a work of art, you can use the lorgnette handle to focus the binocular barrels as well as extend the handle if you wish, or detach it and stow it away in your purse. Imagine, attending your next opera with these in tow! The eyepieces are marked for Lemaire Paris and M.F. & Co (likely the retailer) Marking the binoculars are patent numbers typical to this make and model as well as the small Lemaire bee logo, having 12 Lenses engraved on the top bridge. In very good condition with good focusing and lenses are clean and clear. The binoculars alone measure 3 7/8" across the barrels x 2 1/4" tall, extending to a height of 2 7/8". The lorgnette handle measures 5 1/8" long, can extend to 8 1/2".
