Is there some way to see what version will be installed by an installation disc? I made a USB installer and I forgot whether it's CentOS 7.3 or 7.5. Short of running the whole installer and seeing what happens, I can't see any way to get this info from within Anaconda.

From a end state perspective, it does not matter . . yum update after the install (of either) ends at exactly the same place.
If you know the filename of of the iso, you can tell the difference. (7.5.1804 vs 7.3.1611)
Also, a 'uname -a' from the command prompt will tell you ..
7.5.1804 uses kernel 3.10.0-862 7.3.1611 uses kernel 3.10.0-514
But, as I said .. the answer really does not matter, because the end result of a yum update after the install is exactly the same (7.5.1804+updates), regardless of if you install with 7.0, 7.1, 7.2, 7.3, 7.4, or 7.5 versions of the iso
or any of the rolling isos here:
https://buildlogs.centos.org/rolling/7/isos/x86_64/
If you install from any CentOS-7 ISO .. and run an update , you always end up at the latest version with all updates installed. That is also the only version which is tested at any point in time. (latest + all updates)

I will not be running any updates, because I need to keep a specific old version for software compatibility. I don't know which ISO the USB stick was made from.
Also, a 'uname -a' from the command prompt will tell you ..
This would be perfect; how do you get to a shell from the installer? I only see the option to install.
That is also the only version which is tested at any point in time.
(latest + all updates)
Tested by whom? Each software vendor may test and recommend differently.

From the UI of the installer, <ctrl><alt><f[2-5]

I am talking about the CentOS Team .. The CentOS Project only tests CentOS-7 (or CentOS-6) as the latest version with all updates installed.
We do not maintain any older versions .. so the only valid install is the latest tree with a yum update run.
If you look on mirror.centos.org in any path other than the LATEST for each major version, you will see this:
http://mirror.centos.org/centos/7.4.1708/
(that is from 7.4.1708 branch)
It says this:
======================================== This directory (and version of CentOS) is deprecated. For normal users, you should use /7/ and not /7.4.1708/ in your path. Please see this FAQ concerning the CentOS release scheme:
https://wiki.centos.org/FAQ/General
If you know what you are doing, and absolutely want to remain at the 7.4.1708 level, go to http://vault.centos.org/ for packages.
Please keep in mind that 7.4.1708 no longer gets any updates, nor any security fix's. =========================================
