Is this a factory alternator?

[Dylandeuceman95]

Hello guys, quick question. Realized the truck hasn’t been charging today after investigating with the voltmeter it seems as if my alternator isn’t putting anything out. Now my question is if this alternator looks to be factory or not. It does not look like it to me, but I wanted others opinions that know these trucks more than I do. My hope is to take it off and send it to be rebuilt.

That looks like a 24v delco or clone

More pics might help id.
If it is what I think, you should not need to rebuild as they should be readily available.
