[meteorite-list] heavily encrusted dark grey interior - large find?

[Phil Morgan]

Hello everyone,
I've received very similar stones from multiple sources and was
wondering if anyone else has noticed these.  I would think it must be
a find of decent size.

They are heavily encrusted, but not just caliche and such - lots of
sand and small stones stuck in it.  I've also noticed small brassy
flakes (pyrite?) stuck to them.

Here is a picture of a cut face:

And here is a picture of the exterior:

Even if you haven't seen these in person, any observations would be appreciated.

Regards,
Phil
