LEICA M4 Rebirth | Photography Friend

This 1967-produced, No. 60, black LEICA M4 was a collection of Norwegian photographer Paal Audestad for many years. He plans to have Leica repair this old camera. The traces of time are evident on the body of this LEICA M4, and due to discontinuation, its parts from ten years ago cannot be replaced. Can this old camera be reborn?
