[Untested] Lens for film camera from about 30 years ago

I found this lens for a film camera in my storage room at home.

★ This item's functionality has not been confirmed. Also, it's about 30 years old.

I'm not very knowledgeable about cameras myself, but I thought there might be someone interested in older products, so I'm listing it here.

★ The lens is marked with "Kenko," "MC," "SKYLIGHT," "[1B]," "58mm," and "JAPAN." It also says f=300mm.

★ The caps on the lens are marked "Topman" and "OLYMPUS," respectively.

★ When looking through the lens from the larger side, I think there's a bit of cloudiness.

★ Please check the condition in the photos.

★★ As I mentioned earlier, I'm not familiar with film camera products, so it may be difficult for me to answer any questions.

However, if you would like photos of specific areas, please feel free to let me know in the comments section.

Again, this is an old item. I don't know the extent of any damage inside the lens, so please understand that as well. If you understand this, I would appreciate it if you would consider purchasing this item.
