Well played sir.
I will add to the OP that I just recently discovered some mild pitting on a pair of 35 year old Normandy cones and dressed and polished the pitting out of the races on a lathe. Reinstalled with fresh grease, new balls, and some careful adjusting. Went right back to almost daily use. While the jury is still out I'm sure, I check them after every ride and they still roll smooth as butter.
