I think I see what you're saying. I will try to get a better picture up.
I think I can see where these "nibs" are removed/missing, a slight notch of sorts in the edge of the binding at the fret ends. I believe you guys are right, a fret job sometime in the past.
Unfortunately I have no LP with a bound fretboard to compare.
But also, if re-fretted, a well done job, I am getting used to the light touch required, and I do like the low look, it does seem to fit the instrument.
Thanks again, all
