A useful antique 19th century horn cased magnifying glass, double lens loupe A superb antique Scottish or English horn case magnifying glass Glasses measures 20 mm across, and can be pushed or pulled out either side. It can be used separately or together giving an outstanding strong magnification. There seem to be no damage on any glass, nothing broken or torn but some chaffing on the outer edge of the casing. As useful today as 150 years ago…. Fabulous! #iHelpCPT
