MF20 alternator

My MF20 (w/ 3-cylinder gas)
Automotive tire Vehicle brake Motor vehicle Helmet Alloy wheel
has a Delco-Remy alternator with 13-4 casting.
In the years I've owned the tractor, I don't know if the alternator has ever worked and have gotten away with keeping the battery on a tender when not using it, but have decided to bite the bullet and fix it properly.
I'm not sure if this is the style alternator needed, and what's a good source for a replacement.
Can anyone confirm?

Thanks, Hacke !!
Great information, and it looks like the same alternator I have!
I've got some reading to do now, then when I get back out to the farm I'll do some testing on what I've got to see if I can figure out what the issue is: wiring / voltage regulator / alternator.
