Classification of German fuzes

[FZG76]

Hello


Many people have tried to make a classification grouping the German bomb fuzes in series as AZ 73, 3 for mechanical fuze.

Whenever we see the second digit 3 but that means the first digit? In the example, the number 7 ???

Someone has a good classification ?

Best regards

Thanks Lulus.
It is a picture of the series 0-9, but that means the first digit.
