Welcome to TreasureNet.

The fuze's dome-shaped "cap" sitting atop four tapered brass rings, with multiple tiny lines (time-duration markings) on the third ring, indicate to me that it is a European (possibly British) copy of the Model-1907 US 21-second Timefuze for Shrapnel-Shells. A very similar version of it was used in World War 2.

Explosive "blasting" shells had a thick-walled body. The fuze-less projectile in your photo shows its body is very thin, which proves it is a Shrapnel shell. (The term "Shrapnel" means the shell contained may small antipersonnel balls or slugs.). Shrapnel shells always used a Timefuze, like yours, so that they would explode in the air, scattering their antipersonnel balls among enemy troops, instead of exploding when they struck the ground. The thin-bodied shell in your photo indicates my identification of your fuze as a Timefuze is correct.

About the three images I'm posting (below):
The closeup photo of the US-made version (whose cap is slightly different from yours) unfortunately does not show the time-marking lines on the 3rd ring very well. The other photo shows the fuze in a Shrapnel shell which has been cut open to show the interior of the fuze and the shell. (The antipersonnel balls in it have been removed.) The third image is a British diagram made in 1915 which shows your type of fuze in a Shrapnel shell, with the antipersonnel balls in the shell. But as I said above in this post, the "cap" on your fuze is shaped a bit differently, so I believe it is a European (perhaps British) copy of the American 21-second Timefuze.

Pretty close to this Krupp 77mm AA fuse. The calibrations are every 50 meters of altitude.

20th-Century artillery projectiles and fuzes almost always have manufacturer identification markings (and often, a time-date) on them. For example, the US Model-1907 timefuzes have identification markings stamped into the brass on the lowest ring -- see the photo at the end of this reply. I suggest you gently clean the greyish-white oxidation off your fuze and look for any identification markings.

Also, the brass powder-casing for artillery projectiles usually have manufacturer and time-date markings stamped into the casing's base. If you have the powder-casing for the shells in your photos, look for the manufacturer's markings stamped into them.

I'm not sure on this one, but the little hole above the lines is where the fuse wrench goes to set the time. It is similar to the ones I've used on 60mm, 81mm, 4.2 in mortar and the 120mm.
