Hello,
I'm hoping there are some former phototypesetting workers on here or possibly some folks who are knowledgeable in that area. I'm desperately hoping to accurately ascertain a certain font used in various magazines in the 1980s. I've included some examples below from three separate magazines.

Here are the examples:

The fonts are neither Signa nor Univers (the G and 9 are slightly different). Any help is greatly appreciated. Thanks so much!!
