Hello, I have a Leicaflex Mark 1, and its serial number is 1083673. When I checked, I saw that it was in the first batch produced (1080001-1085000 Leica Leicaflex (1-chrome+black) 1964-1965 5000 Batch). I live in Türkiye. A repairman told me that these cameras break down frequently and frequently. He also said that repairs are difficult. What are the common malfunctions of these cameras? Is the repairman telling the truth? The economic crisis in Türkiye is putting pressure on repair and film costs. It's also difficult to find a good repairman in Türkiye.
