does anyone recognize this engine?

[ning]

12v I6 with a curious (to me) valve arrangement
might need a bit of elbow grease but was recently running (?50 years idk)

"Ran when parked "!

The part number on the valve brings up the Hercules QXC flat head engines.

If anyone wants the parts manual to make it running, here it is: https://www.tractorparts.com/PDFs/HERCULES_QX_SERIES_6-CYL_ENGINES_PARTS.pdf

Wonder what those valves are made of that didn't rust, wouldn't be stainless I wouldn't think.
