ID Barometric bomb fuze

[MINENAZ16]

Hello,

I can't remember where I found this picture. I think fjordhouse has one example.
Looks like a British bomb barometric fuze but what is the nomenclature ?

Regards

We well know the No860 with a different body, I assume it's the MkII we usually find !
So know I understand what means the doc about the two diameters of MkI body.
I notice that many people are mistaken about identification of 860.
