Led Zeppelin II Serif - Old Style?

Does anyone know what this serif is please? Apologies for the poor quality scan.

The capitals look very close to Belfast Serial Light (or extra light) by SoftMaker but I have no clue about the lowercase

Thanks. I don't think that's it though as the M and W are wrong. So are the numerals. It's very similar to Cochin. Garamond, Goudy etc, but nome of them are quite right...

Looks like Goudy’s work.
After doing some research I suspect this to be Pabst Roman done for ATF, not digitized.
Goudy later licensed Pabst Oldstyle to the Lanston Type Library.

Having no samples of Pabst Roman to compare, I thought I'd throw out something that looks mighty close to the blurry image provided - Egmont.
