It turns out that when you download the Mountain Lion installer from the Mac App Store, that copy of the installer installs whatever version of OS X was available at the time of download. One of the coolest ways to get familiar with the Terminal is to use it to open files. I had found it difficult to get an overview of what was different about Terminal and Mac's bash vs. Other Unix / POSIX / Linux shells. Some unhelpful advice on the web was that you could pick up any UNIX book as Mac Terminal is 'mostly' the same. But if you don't know which commands count as 'mostly' and which don't, that advice is quite useless. To log into your Mac on another Mac, execute the command: ssh -l username remote-address. Replace username with the username you'd use to log into OS X and remote-address with the IP address given to you in the Sharing pane. You can now control your Mac and execute Terminal commands remotely, a real plus.

The

During my testing in the Catalina beta version I was able to download 10.15, 10.14.6, 10.14.5, and 10.13.6. I was not able to test if 10.13.6 would download the hardware specific build of 10.13.6 for the 2018 MacBook Pro, since I do not have that hardware.
So, to pull 10.13.6 down, you’d use:
softwareupdate --fetch-full-installer --full-installer-version 10.13.6
Retro flip clock screensaver. I wish Apple would just have a support document up with direct downloads for all of this stuff, but this tool is not a bad alternative.
