Copleston's history of philosophy font

What is the font used in Copleston's history of philosophy? I think the book was published by Doubleday Image Books. Thanks for helping

Monotype Old Style seems to have the right letterforms but the digital version at fonts.com seems not to include a thickened hairline version like the old metal type apparently used for the book. Has anyone done a "text" or "book" version of Monotype Old Style, or its general equivalent?
