Finding the right type…

The closest type faces I can find are Perpetua and Arno Pro, but both of them are wrong.
No “Th” ligature in Perpetua, and the one in Arno has a rising serif that the orig. doesn’t. The italics of both Perpetua and Arno are totally different than the orig. found on TSR.
There’s a typeface I don’t have called Lapidary 333, but there’s just a really good chance that I won’t find a digital version of the typeface.
Notice that the two books are actually set in different faces, or, at least, variations of the same face. The lowercase "y" in both are drastically different (see 5 at the bottom of image).
