I found this while cleaning out my parents' house. What is this? I don't know what it's used for, but I think it belonged to a camera-loving relative. There is dirt or scratches on the lens (red circle in the image). There is mold-like dirt on the inner lens (yellow circle in the image). I don't know what it's used for, so I'm not sure how to price it, and I've set a tentative price. Please feel free to negotiate the price. This item has been stored at home for a long time, so please refrain from purchasing if you are concerned.
