Need help with an ID of this ordnance round

[WJT]

I would like some help to identify this round.

I would also like to know if it would have been used by Austrian Submatines during WW1.

Thanks,

Bill

What are the dimensions? Bore size, height of casing, any stampings, letters, numbers?

Bill - I have magnified to 400 times and the second word would appear to be Budapest.

I would hazard a guess that it could be an anti-aircraft shell - as for a Bofors. The alternative

is an aircraft or, tank ? I hope someone can identify it identify it for you. Mervyn

With those rings on the nose I'd have to agree that it's probably an anti-aircraft shell wherein the shells could be set to detonate at certain heights. There would be little reason for a submarine to have this kind of ammo. For the caliber just measure from one side to the other at the point where the head and brass casing meet. The early Austrian submarines U20 class carried a 20mm (2.6 in) deck gun, they were succeeded by the U27 class with a 75mm (3.0 in) gun and late war the U43 class had an 88mm (3.5 in ) gun.
