Antique Windsor Style Eyeglasses with case

Very old style Windsor specs in a case. Nose clips were invented in the 1920s, so these may be about that age or older. The vintage glasses are in overall good condition and the lenses look to be in good shape. No idea what the prescription would be. Lining of the case is starting to come apart inside, but it’s done it’s job keeping these spectacles safe for all of these years.
