UNIV.SHX is a commercial custom SHX font, part of the Ausfont series produced by Graphic Computer Services, a company based in Western Australia. But as far a I can remember, that's not a bigfont. We bought a copy in the 80's, so I don't know if the company still exists.
What you can do, is make a copy of a bigfont and call it UNIV.SHX. There aren't that many bigfonts, so maybe this is also a copy (that is modified?).
