Vintage Opera Style Glasses or Small Binoculars

A very nice pair of Trojan opera style binoculars made in the USA. They have an unknown magnification, but they are in perfect working order. There are some scratches but no defects in the optics. The outside is black with a black leather cover. Overall, the glasses are in very nice condition. the damaged leather case appears to be original as it conforms the the glasses form. This case does protect the optic and may not be salvageable, but will work to protect. These are a very small pair of binoculars, only 2 by 4 inches in size when closed and opens to 2 3/8 inches. there is some wear evidence on the glasses, but very minor.
