Greetings Everyone. GB it does look a little weary in the current condition. But maybe this helps...
Option 1 - It's Junk - Whatever you do can't make it worse.
Option 2 - It's gonna need regrinding - You probably can't remove enough if you don't get medieval.
Option 3 - It's ugly now, but wait - Hit it with something? You can always go back to 2 and 1.
Would you guys use Evaporust/Rust911? Would the 'blackening' be a problem?
Then something to see where the pitting ends? Scotch-Brite is pretty gentle, and you can step up/down in 'grit.' A wire wheel sounded like an okay suggestion, but carefully.
