Early Victorian Lignum Vitae and Brass Library Glass or Gallery Glass

For sale, an early Victorian Lignum Vitae and brass Library Glass or Gallery Glass. Comprised of a brass surround holding a six-and-a-half-inch lens with a turned lignum vitae handle connected by a generous brass ferrule. A very generous size of its type with an unusually pleasant choice of handle wood, some scratches to the lens exit requisite with age but it does not affect its function. An imposing magnifier which would have been used in either a library or gallery setting to allow closer visual inspection. Circa 1840
