unknown 85mm HE shell??

[Krt7.92]

Hello,

lenght: 35cm, diameter: about 85mm, diameter driving band: about 90mm.
It came without a fuze but a US M54TSQ fuze fits well. Only marking is "15" on the side of the shell. Looks repainted.
It has all features of a HE-shell, but: genuine or "home-made"?

Thanks for your replies!

The driving band looks strange, otherwise it seems to be a 25pr HE

looks like it has filler on it and a 'new' band, looks 25pr BE to me.

I compared it with a 25Pr HE and indeed they are almost the same besides the driving band which is much larger. I'm thinking it could be post-WWII production? I found an image here of a fired 25Pr shell that was made by the belgian company MMJ. The driving band looks the same width as mine?
