I thought I had the page with photos bookmarked, but it seems I'm not as OCD as I thought, but I believe they were on a page in an old forum thread here.

(Scroll down until 10C Series Versions)

The link says:

Quote:Late versions of the HP-11C, 15C and 16C were made with HP-12C keys that were either (re)painted or were made using worn molds for other keys.

Personally I have only seen the latter, double shot keys showing a ghost labelling from worn out mold.
