Jussi,

Several Leica books include tables of years and serial numbers. There is 
no formula that I know of; lens production varied quite a bit from year 
to year. 

The Summicron is from 1970, the Tele-Elmarit is from 1982.

I looked this up in _Identifying Leica Cameras_, by Ghester Sartorius. 
The photos of the cameras in this book are by Lino Manfrotto, who makes 
the tripods and heads that are sold under the Bogen name in North America.
