I have a lens in a wooden box. It looks like it's a copy lens. Plate on box says Apo-NIKKOR 1:9 f=480mm NIPPON KOGAKU MADE IN JAPAN. Fitted box has lens
with hinged lens cap, 5 metal plate with small aperture that are on a locking pivot, 4 metal gel filter holders??? and a signed certificate. What do I have?
Does it have any value? INfo would be appreciated. Thank you Look at photos
