The seller told me the items came to Denmark from Sweden as metal scrap from a bofors factory many years ago together with all kinds of random trash metal, and was picked by his friend at the scrap yard.
So now im here hoping for someone to take a look and know what it is

The 'bomb' The tail is 38 cm wide and the whole thing is 54cm high and is solid aluminum. I however cant find any markings on it.
The inside of the 'cone' part connecting it to the missing parts is covered in some kind of thick fabric like paper.

Large bomb tail ? Possibly from Bofors in sweden ?
