adan Posted February 14, 2016 Share #2 Â Posted February 14, 2016 Leica serial numbers are not perfectly definitive. For a long time they were pre-assigned - before manufacture - in blocks. They may still be. Â As in your example, 1000 sequential numbers were assigned to be used on silver 50 Summicrons. Â Once manufacturing begins, there may be a mismatch in supply and demand - more black lenses needed, and less demand for silver than anticipated. So some of the 1000 lenses are made in black. Â Additionally, it may take 18 months to make and sell 1000 50 Summicrons - so while the numbers were assigned in 1994, any actual lens may have been made in 1995. Less so for a popular lens like the 50 Summicron. But an exotic lens like a Noctilux or 75 Summilux may take 10 years to "use up" 1000 serial numbers. Â Serial numbers, for Leica, are just a way of keeping track of any one specific lens or camera (When did it leave the factory? Which country/dealer/consumer did it go to? Has it ever been back in for servicing?). They don't care if it confuses collectors and aficianados when things don't always match the records.
