Small marking in Leica lens

Hi,

 

I have a question.

I got a few latest Leica lenses and just realised that there is a small double-digit number beside the "m" marking in the focal range on the lens.

Please advise what the number means. Thank you.

Denotes the exact focal length of the lens. If a 50mm lens is marked 43 for instance, you have a 54.3mm lens.

Leitz also marked the exact focal length in other places.On my 135mm f4.5 elmar,the exact focal length is scratched on the inside of the lens and is visible when the lens head is removed.

Yes,

 

This was done mainly on lenses with removeable heads - often just written in pencil. The focusing unit should have the same number written or scratched as well.

Yes,the focusing mount and the lens head have the same serial number as well as the exact focal length written in pencil.
