Question on Reblue of Ithaca NID with Ivory Beads

[Joe from MO]

So, I have an Ithaca Gr II 16ga NID that has dual Ivory Beads.

The bluing where the gun has been held over the years is quite thin.

I am having a local gunsmith repair the trigger guard, but he did not feel comfortable rust bluing the barrels with the Ivory beads.

I am flip flopping on even having it done, as the barrels have a nice patina to them, and I just will have to make sure I don't let them sit if they get wet.

But... If when I get the gun back, and I decide to so more of a full restore of it, who would you guys recommend as a good gunsmith to do this. Is it possible to have done, withouth damaging the ivory beads, if it's not, that's a deal breaker as I'd rather keep the ivory beads, and the thin bluing.

Also, about how long a turnaround are people seeing for this sort of work. I assume I could just ship the barrels...
