@RARE@ In Leica screw mount. Released in 1956. 9 elements in 6 groups. Feet scale. Nikon S mount was manufactured quite a lot, yet the L mount is pretty rare, manufactured about only 200.
Slight balsam on inner element and slight cleaning marks on the rear element, yet still clean glass. The barrel has some used marks. The aperture blades and glass are cleaned in 2017. Aperture scale is a bit of gap to the right. *Selling on consignment.
