Gary, you nailed it in one. Although there are some glyphs from other sources, many of the glyphs in this typeface are from Adobe Wood Type Ornaments One.
Which doesn't invalidate this nice gift Bob has brought to our attention, and the metadata credits no creator, but only the program used to build the font (Metamorphosis Professional 2.03, in 1992).
Jon, commercial typefaces don not go by traditional copyright protection. You can copyright the name of a typeface—such as Tekton and Compacta, but the outlines of the glyphs within the typeface are often imitated, so you have "lookalike" typefaces such as "Technical" which is clearly "Tekton", and largely the creator of the typeface is unable to sue or get any sort of compensation for the devaluation of their work.
Once, however, there was a company called SWFTE who offered 20 or so "lookalike" fonts for ten bucks or something, and they were mercilessly busted because they didn't even bother to imitate the glyphs; they copied them from the original fonts, node for node. Bitstream, Adobe, Emigré, P22 and one other company, I think, were able in court to show that there was absolutely no difference between the glyphs in SWFTE's fonts and theirs.
This was a historic, but unusual suit, because typically you can't copyright the design of a glyph in a font.
The answer to your question, Jon, is no, not enough time has gone by for the names of Adobe typefaces to go out of copyright; copyrights have a 75 year life span now, I believe. But if you're skilled and know how to use a font editor, feel free to copy any glyphs you like—they are not subject to a copyright.
