I have done repairs for many years and was told by older and wiser
goldsmiths that 14KP on a gold piece (not plated) stood for “14 karat
plumb” which meant it was right on the nose 14K, not under or over in
the alloy content. I don’t know how accurate this is, but maybe it
will bring some leads.

Happy hunting!
