While going through my great aunt & uncles belongings to get things ready for an estate sale, there was a bunch of old camera gear and this lens stuck out like a sore thumb. It's a "Universar Telephoto" 500mm f/8 No. H8 1711. It's a big sucker.... 19"-20". Heavy, too. Other than the lens caps, it's all steel and glass. If anyone can give me any insight into this lens, the company Universar, or any remote value, it'd be much appreciated. Thanks!
