Here is the most unusual prototype of the Compur-Summicron 2/5cm lens in aluminium mount. All outer parts of this lens are still of a different design than the 150 pieces from the official production. Even the lens comes complete with a prototype release-arm, which is also different in design that those commonly known. Lens serial number is 1095052, while official production of the Compur Summicron only started from 1152XXX. The similar prototype lens, serial number 1095051, which was published by Ottmar Michaely in Leica Historica e.V. VIDOM magazine Nr. 95 (2008), p.36, achieved a price of HKD550,000 at L&H 2015 Spring Auction.
This lens comes with release arm, both lens caps and a letter of authenticity from Mr. Ottmar Michaely.
