We bought a 90mm brass casing with a large black metal projectile in it. Owner said he purchased them separately and really knew nothing about them other than they fit. We are trying to find information on this projectile if anyone has the knowledge or where we could go to find out. Thanks!

    Let's just hope it's not an explosive projectile!

    You don't have a casing. You have the whole projectile.
    Most likely a anti-aircraft round with a delay/time fuse in the end.
    Note the "rifled" fins. But also possible a frag/shot cannister.
    I will get you the exact model after I find a good pic in my reference
    library.
    still working on it....

    next...possible version of 90mm german anti tank round If the primer hole is not drilled thru into the middle, it's for the tracer compound.
    here's one missing the rifling fins.

    More likely a APT that was fired from a tank gun
    Note that the projo is solid except on the base where the tracer compound would be at.

    HE rounds would have either (or both) a nose or base fuse, that is almost the diameter of the projo.
    In the photo below are 2 HE rounds, you can clearly see the size of the fuse VS the OD of the slug.

    It looks like a fired steel bullet to me. That brass band is smooth until the rifling's get a bite on it. I'm sure that google has Army manuals in PDF that would tell you more. They were using 105 when I was around big guns.

    see the pic on page 11 it looks just like yours but with the windshield in place, yours was shed on impact.

    It's an armor piercing or HE round with a base detonating fuze, maybe French from the markings.
    Run a magnet over it to acertain what you're talking about. It should be steel if after 1900, if actually copper or brass, it will be before 1900.
    The rotating band (the thing with lines cut in it) should be brass.
    I don't see any shell casing so no way to guess what kind of weapon it was fired from.
    90mm has been used by a lot of countries.
