That looks like a mid 90's fork crown, Most likely aluminum, full slope, but not quite a "unicrown" where they just pretty much bend the fork legs into a U, so it's just one continuous tube with a steerer tube welded to it's top. I like this still separate crown much better.
I wonder who made it? Vitus??
Looks like it goes into an oversized headtube.....Could be for later model Vitus frame.
