MIR-1 ZOMZ 37MM F2.8 GRAND PRIX BRUSSELS 1958 M39 MOUNT PRIME LENS + caps

  
I adore this lens, but it isn't getting the use it deserves. The glass elements are pristine, no scratches, no mold/fungus etc.. The knurling on the body is a little dirty but I imagine would be easy enough to clean with some patience and a toothbrush if that's your thing. Included with it are the original front cap with the ZOMZ logo and a 3d printed rear cap. The lens was manufactured by ZOMZ and therefore likely a later model made in the 1960s.
