Mount: M39 (Leica Thread Mount for enlargers)

The Meopta Belar 75mm f/4.5, serial number 115067, is a Czech-made enlarging lens designed primarily for medium format negatives (6×6 or 6×7) in darkroom enlargers. Produced by Meopta, a respected optical manufacturer, the Belar series was known for its sharpness, contrast, and excellent color rendition, especially in black-and-white printing.
