Lowes Home Improvement carries the Portfolio line, but if this came from a locker it has been my experience that items can be 2 or more years old and no longer carried or even manufactued and thus become harder to research.
My GUESS is that it was probably about a $200 fixture...but that is just an opinion.
Something like an old Bose speaker or receiver would be easier of course or an old Nikon camera or an old 16mm projector or an old Jimmy Durante plastic nose. (well maybe not the last one, and most people on these forums won't even know who Jimmy Durante was).
