Question about 81mm french mortar grenade and fuze

[Adrenalin]

Hi guys,

i am new to the forum and i have a question directly.

A friend send me these pictures of this 81mm french mortar grenade with fuze. Grenade and fuze are complete inert. The fuze is iron and there a no stemps on it. The socket is untypical big and had the stamps ABS 15.33.
I have the same mortar as a practice version in black/blue with the markings "EXce". Also with this socket but without any fuze.

My questions:

1. Can anybody tell me a few informations about this fuze ?
2: When is this specially big socket use (only practice or smoke) ?

Thank you, best regards

I think the fuze may be for an artillery shell and not for mortars. That just happens to fit. Looks like a WW1 version German Dopp. Z. variation.

It's a practice projectile with a special gaine

Thank you very much.

The drawings are from belot ?
Did you have any informations or drawings from the suitable fuze "fusée de 24/31mm d´exercice" ?

Best regards.

Not sure but I think it was those ones : 24/31 PRACTICE RYG 18 (drawing below) or 24/31 PRACTICE RY 17
Black powder replaces the detonator

Great !

So, on pic 3, the upper piece isn´t a fuze. It´s a screw for closing the hole....?! That make sense.
Thank you again.

Seems to be a fuze. I don't know which one, but not the right one.
