Identification: Brass Shell Fuse timer

[battling]

I bought a shell fuse timer (pictures attached) in Leper, Belguim sometime ago and I understand that it was recovered from the surrounding area.

Can anyone help me identify this fuse? I thought it was a British type 88 fuse by the look of it, but my fuse does NOT have a slot in the top.

Markings inside are "BMC" "88" "16" and "H" the letter H is within a box (I'd like to know what these mean as well!)

The fuse is about 7.5cm wide - as you can see from the pictures it's a bit battered - and weights 813g.

Hi
It's T&P fuze N80 MK VI or VII on reduced base of Shrapnel shell 18 or 13 Pr

HI
All in brass is for N80 Mk VII not Mk VI
excuse my post too fast

Thank you Doctor.

Couple of other questions:
1) Do you know what the markings stand for? Specifically BMC?
2) Is this fuse off an artillery shell?

Cheers!
