Known in Germany as Kabel fett, or Fette Kabel. Many shapes and the large x-height are quite different from the rest of the Kabel family.
In 1980, Letraset added an even bolder Ultra Heavy to their Kabel series (sometimes spelled Cable). Not the same as ITC Kabel Ultra, which has angled terminals and diamond dots.
Digitized by Bitstream as Geometric 231 Heavy.
