question regarding the French Bouchon Retard d'exercice 2.5s

[orpheus72]

I have this French practice delay fuze.

does someone has a cutaway view or schematic for this fuze?

Also, where were these used? (this one was found on a French MF2 CS handgrenade, but i'm not convinced that's correct)

Thanks.

Hello Orpheus
this delay fuze is not a practice fuze, It is used only as a rifle grenade with a "tromblon" mounted on a sleeve, the F2 CB granate is turned upside down and the gases produced by a special cartridge launch pierce the plastic cap and ignites the powder
