SOLIGOR WIDE-AUTO 24 MM F/2.8 LENS (T4?) À PARIS

This lens is a mystery to me. I believe it uses the T4 universal mounting system, but I can't remove or even identify the bayonet that's on it right now. The notch makes it looks like Konica AR, but it won't mount on a Konica camera. Also, there's the bit of metal ring that's bent upwards -- I can't tell if that's supposed to be like that (it might fold down easily if mounted on a camera) or if it's damaged.  The lens glass is in very good condition, clean and clear with no fungus or haze. The mechanics feel good but the iris is sluggish.  Feel free to message me if you know what this thing is.  -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- About Camera Sanctuary: Like you, I love cameras. I bring all manner of equipment into the Camera Sanctuary in the hope that I can place it in a new home. I handle everything from collector’s pieces to total beaters, Leica to Lomo, Alpa to Argus. You can buy from me secure in the following: - My descriptions are honest. Some cameras have been babied, and some have been brutalized. There’s room in the world for both, but I won't try to sell one as the other. - I won’t pretend I don’t know things.  - I’ll take back anything that doesn’t meet your expectations.
