This is Benjamin. Franklin Gothic, but not quite. It’s barely at 0.0.1, with only some capital letters, from scans of old type catalogues found online.
The Ultra Condensed master is loosely based on the existing Extra Condensed but adjusted from 56% to 50%.
The Ultra Expanded master is based on more math than I’d done in all the years since I left school.
There are issues, of course. Spacing and kerning need attention. As do the counters on the extremes. And more masters are needed.
