Please Help me ID these Parts

[MMasa]

Does anyone know what this oil pump goes to? It may be motorcycle or automotive. It was in with a pile of teens and twenties JD parts.



How about this regulator? It was in with a big pile of Panhead, Shovelhead, Sportster parts that I picked up a few years ago.
Thanks

I lightened the pump pix a bit.
