How can I figure out the font used by a class file

Question

I have a document class that isn't as thoroughly documented as I might like, and I'd like to figure out what font it uses. Is there an easy, universal way to get TeX to tell you directly what font is being defined by the class file? Preferably in a way that will show me how I can define the font in my own file, in TeX code?

I have read this question that asks how to find fonts in pdfs. This doesn't tell me what the font is called in TeX, and is very round-about. Preferably, I'd like to know the name of the font package that I want to use.

If you produce some pdf with that class you can check the pdf properties to see the used fonts. — Sigur, Dec 16 '14 at 23:51
If you're referring to the font that is used to generate some output (PDF), then you can following the guidelines in How do I find out what fonts are used in a document/picture? (possible duplicate). — Werner, Dec 16 '14 at 23:54
That does look like a duplicate - didn't find it in my search though. — T.C. Proctor, Dec 17 '14 at 00:54
@Werner I know this is five years old now, but this question did get distinct answers from the one's in the document/picture one. I think that I really did have a distinct question here - I have the TeX file of the document, and I want to figure out how TeX is defining the font. — T.C. Proctor, Apr 17 '20 at 17:37

The document

\documentclass{article}
\begin{document}

\expandafter\show\the\font

\stop

puts the following information on the terminal and log

\OT1/cmr/m/n/10=select font cmr10.

showing that article is using the font cmr10 known to latex as

\fontencoding{OT1}\fontfamily{cmr}\fontseries{m}\fontshape{n}\selectfont

Just replace article by any class you wish to test.

It helps to precede this statement with \wlog{ ... } so you can find it more easily in the log. – Steven Jeuris Feb 14 '17 at 12:47

@StevenJeuris I was assuming running in interactive mode where \show stops and shows the tex as if for an error message – David Carlisle Feb 14 '17 at 13:50
