Why this rock is probably not a meteorite:
This might be a meteorite in that it contains tiny blebs of metal
and it has a coating that might be a fusion crust with flow marks
(see lunar meteorite NWA 482).
The problems are (1) the interior is glassy, not crystalline as in
nearly all meteorites and (2) and the glass contains many small vesicles.
This thing was once molten. Meteorites don't have vesicles
like this because, with very few exceptions, meteorites were never
molten. Those that were molten usually cooled so slowly that the gas
bubbles escaped and crystals formed, not glass.

What is it?
Probably a piece of slag. The "crust" is fast-cooled scum
that formed on the surface of molten material.
It would be good to get a chemical analysis on this one.
