Designation of the British fuze

[lcn]

Hi
I would like to know in which year the British fuzes changed name, in passing the name of fuze in a number.
For example the fuze time 15-secs ML became No. 41
What is that somebody would have the list of all these changes?
Thank you in advance
Au revoir
Jean Paul

Hi JP
Since 1887 an orderwas promulgated giving existing fuzes distinct number.
