Trevor Johnson was kind enough to dig through his old job files, and let me know that the display type on this design was custom lettering by Pat Hickson (images of the rubylith key art are attached, downsampled slightly so they would upload).
While Pat and her husband, Paul, have designed a number of typefaces, this does not appear to be a design that was made into a commercial font.
If you look at the rest of the art, the terminal angles on the h and l are distinctive and not found in combination with the other details (the ball terminals, the straight serifs) in any typeface I can find.
Pistilli / Eloquent, with a bit of editing, is probably your best starting point for recreating the look.
