I can concur with Eric's evaluation. I recently recieved 2 Pluses. One Plus and one
upgraded original. The original still has the front piece of the case with a new
platinum "Plus" label case piece.
The 128's front piece will have the S/N sticker on the ledge under the monitor and the
Plus will have the S/N sticker on the bottom of the case.
I can check the boards to see if there are any difference between the boards.

I think all machines sold as the Macintosh Plus have the words on the front. Its only
upgraded machines that don't. Apple sold a Macintosh Plus upgrade kit that included a
new case back (beige, obviously, to match the old case front), so there are a lot of
them out there, but they did not start out as Pluses.
Not sure when the color changed from beige to platinum. Apple changed the label on the
back from "Macintosh Plus 1Mb" (with a copyright date of 1987) to "Macintosh Plus"
(with a copyright date of 1988). It is possible that the case color changed at the
same time, but it is also possible that it changed before that. As far as I know, from
asking a seller on eBay, the upgrade case backs say "Macintosh Plus 1 Mb" but they do
not have a copyright date. So it is also possible the case color changed when the 1987
copyright date was added to the label. It does make sense that Apple would have
stopped making the upgrade kits in 1987, and so there would no longer be any need to
keep the case color beige ("putty" is really a better description of the original
color--and don't get me started on "platinum").
The platinum machines had new ROMs in them. See:
http://developer.apple.com/technotes/hw/hw_11.html
Unfortunately the note doesn't say when the new ROMs came out, but 1988 seems awfully
late and 1987 more like it.
In sum, if I were a betting man (and assuming the eBay seller did not miss the date),
I'd bet that all beige machines say "Macintosh Plus 1 Mb" on the back with no
copyright date. All platinum machines say either "Macintosh Plus 1Mb" (with a
copyright date of 1987) or "Macintosh Plus" (with a copyright date of 1988).
