Hi Yves,
this is very close to Parsons Heavy by Dieter Steffmann (with the exception of /P)
The copyright says:

This makes sense. The sample is definitely pre-digital, so probably the “original” typeface. Thanks!

Find Parsnip but not in bold weight.

You'll notice that the Swash caps Nick used in Parsnip do not match the P in the sample. Nick's are the same as the ones shown for Parsons in McGrew's book on "American Metal Typefaces..", so this tells me the P in the sample was a customization, and not from the original design. In fact the swash initials were not in the original design — Sidney Gaunt designed them, and Ransom did not approve them all, yet McGrew says they were cast by BB&S.

Here is the original font , from McGrew's book _American Mental Type_, rearranged for the narrow window format used by Typophile
