1975 - Leica Summicron 50mm Rigid

THIS LEICA M RIGID LENS, SERIAL RANGE 2731922 - 2731950, BELONGS TO AN EXTREMELY RARE BATCH OF EXACTLY 29 UNITS. PRODUCED IN 1975—YEARS AFTER THE OFFICIAL DISCONTINUATION OF THE RIGID STRUCTURE—THIS WAS A "MICRO-ADDITIONAL PRODUCTION" LIKELY TRIGGERED BY A SPECIAL ORDER OR THE UTILIZATION OF REMAINING COMPONENTS. THIS IS NOT A STANDARD MASS-PRODUCTION UNIT, BUT RATHER THE ABSOLUTE FINAL ITERATION OF THE RIGID SERIES. WITH A RARITY PROBABILITY OF 1/29, THIS LENS REMAINS IN PRISTINE CONDITION. OUR ANALYSIS REVEALED THAT THE SERIAL NUMBER ON THE EXTERNAL FOCUSING RING DISCREPATES FROM THE INTERNAL OPTICAL CELL SERIAL NUMBER. THIS FURTHER CONFIRMS THAT THESE 1975 SUPPLEMENTARY RIGIDS WERE ASSEMBLED FROM EXISTING INVENTORY TO FULFILL SPECIFIC CONTRACTS, MAKING THEM A FASCINATING HISTORICAL ANOMALY.
