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 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?
