These two little books about Leicas are very useful, as is the third book; get the latest edition you can find.

Online you can get a lot from the serial number here:-

It's in French but obvious how to use it. Here's a clue "Objectif" is the same as "Objective" and "Boîte" means body. The answer after you put in the serial number is pretty obvious.
There's also a very useful list and detailed list of serial numbers and bodies at the back of Rigliatti's book "Leica the first 70 years".
