Nickel-finished Hektor 5cm f2.5. No serial number. Uncoated. Marked with a 0 on the back of the focusing knob. Optical construction of 3 groups and 6 elements. Distance scale in meters. Full rotation helicoid.
This piece is believed to be a Hektor lens originally supplied as standard on a Leica Model A around 1930, later officially converted by Leitz to Leica L mount. Many Hektors of this type clearly have a shorter barrel, but this one has a barrel length close to that of a regular Hektor at first glance.
This variant is extremely scarce, and most examples have been heavily used, but this one is in exceptionally fine condition.
An outstanding, unnumbered Hektor with excellent imaging performance.

Light scuff marks can be seen near the nameplate and on the collapsible barrel, but for a nickel Hektor, it is in very fine cosmetic condition. There are no dings or distortions, suggesting it has been carefully handled over the years.
It appears to have been properly serviced under the previous owner, with excellent operational feel and perfect rangefinder coupling. Both the aperture and helicoid operate smoothly. The front element shows only very slight wipe marks, and otherwise the glass is remarkably clean for a Hektor, with no noticeable scratches or haze.

Test shots produced excellent results, with elegant rendering that combines softness with fine detail. Rangefinder coupling was spot-on, making shooting an enjoyable experience. Sample images are posted in the test gallery, all taken wide open without a hood. The good condition of the glass likely contributes to the fine color reproduction and strong, well-defined rendering.

Comes with genuine front and rear Bakelite caps. A rarely found condition.
