The rod has been sawn off. Has a brass pin holding steel insert. Different diameter to cut under the detonator plate (bit missing?)
Dimensions are:

150mm overall.

46mm diameter
35.5mm detonator plate diameter.
10mm rod.
1.75mm thread pitch. (or 14 TPI?)

Hello,

I think you have a rare and nice example of Belgian Saint Chamond grenade for 142mm mortar Delattre-Saint Chamond (ww1)
