Need help identifying fleemarket find

[Widgren]

First time poster here. This sunday i went to a local flea market and found this! The seller claimed it to be found at the continent and that it was a howitzer round from wwi. I have no idea and my childlike atempts at research into an are i know very little about yielded only one good thing. This forum! It is about 84mm i diameter at its fattest and 23 cm tall. There are some inscriptions too.

Underneath there is a small sticker with "haubitz on it.

If you need better photos, more meassurements or anything just let me know and ill post it.

it's a really nice swedish shell: "8,4 cm vningsgranatkartesch m/1888" the fuze is called "26H Dubbelrr m/1885"

I am not 100% sure, but I think it is for 8,4 cm Krupp guns.

I bought it in sweden so that sounds resonable. Ill check it out. Thanks!
