The Western-style slab serif with flared bottom halves was drawn by Ed Benguiat for Photo-Lettering, apparently as spinoff of Benguiat Serendipity, which is a more conventional Barnum (with Benguiat Buffalo being a rounded version). The all-caps Zenedipity is shown in PLINC’s Alphabet Thesaurus, Vol. 2 (1965) in two widths. Athird Wide style is initially listed as exclusive design. It’s shown in Vol.3 (1971). I’m not aware of a digitization.
