Can't find it in the "Purchased" tab.

Make sure you're logged into an appleid that actually downloaded it before.

I used Mavericks about 4 years ago on my old PC but I can't remember if I used an Apple ID to download it. Any other way to obtain it?

I don't understand this statement...
No way to use the App Store without an appleid.

No idea then. I logged in with my second ID and I don't have it there either. Do you still have it in your list?

Currently, I don't have any system running an old enough version of the App Store to have the purchases tab.
But I do have all OS X/macOS installers archived.
