This extremely early and rare Leica Summicron 90mm f2 chrome M bayonet mount lens is in excellent condition cosmetically, mechanically and optically. Serial #1983111. Extremely late serial number first version. Very unusual example. Serial number indicates it was made in 1963 but production ended in 1962. A very late production example. An extremely rare all black finish version lens with the with the dual scale red/white feet/meter focus scale. Comes with matching black finish 16462 Visoflex focus mount. Also has the hard to find preset aperture control ring instead of the standard aperture ring. I just sold one of these recently in mint condition for $1895 USD. In excellent condition overall. A must have.
