Be careful, the body isn't aluminum, it's incendiary electron, magnesium, thermite or similar. They appear in Spain, but I don't know what is it.

This is awfully interesting.
The tail construction is typical of the 1916-17 French makeshift bombs made with artillery shells (75mm and above "obus empennes"). Although this is definitively not one of these French bombs.
This raises two questions, beyond the issue of the French influence behind its conception: 1) how is it fuzed? 2) can the body of this bomb be a mortar shell (or incendiary grenade or other "re-worked" shell)?

I was thinking it might be a pneumatic mortar projectile

Just to illustrate what I am speaking about concerning 1916-17 French makeshift bomb tails:
