I found information on this Bofors designed 71mm Lyran Illuminating mortar shell as used on AFV's and by Infantry and Navy.
Apparently the mortar can also fire HE and smoke shells too. Used from mid 1960's.
The fuze has a safe position and 1, 2 or 3 dots for different range settings . (info from the net).
What is missing from the fuze centre on this example? I could not find any photos of the shell to compare.

Hallo @ron3350,
there seems to be nothing missing from your fuze. The square hole in the center seems to be a keyhole for setting the fuzedelay. Switzerland also introduced this model and manufactured it in licence from Bofors. The interesting thing about this fuze is, that it uses the same system as the 150 year old belgian Bormann fuze with a horizontal powder train delay. Attached are 2 fotos from the nice swiss book "The Fuzes Of The Swiss Army"(in german)
