With a serial number you can not only know when the lens was made, you can also check for potential issues, like if someone is trying to pass off a Summicron ...

Lens Serial Numbers, Year. 100 000 - 135 000, 1931. 135 001 - 156 000, 1932. 156 001 - 195 000, 1933. 195 001 - 236 000, 1934.

I have heard that from a serial number, it is easy to find the year the Leica lens was made in. If so, how do I do it? Many thanks in advance for your help.

Leica made lens number 1,000,000, a 50mm f/1.5 Summarit, on 24 October 1952, at which time they already had over 100 years of optical experiance.

I've been searching for a 50mm lens date coded to 1967. There are two sites that are quoted often when referencing Leica lens serial number identification.

Serial 2974251 to 3880946. 10 aperture blades. Exists with Yellow /white and red /white focusing scale. 35mm, 2.0. 11 310. 1979.
