Nice one Richard, though I think we might be dealing with the softer cage 
bracket that’s engulfed and with callus overlapping….bah.
So likely a few zips vertically on the main stem with a disc cutter and 
prizing that part with a jenny or such like.

One of the points to come out of Jim's post is that if the grille is cast 
iron, a careful blow with a big-enough hammer might break it, rather than 
having to bring an electric grinder to the situation to cut it.

The photos were taken at the time and about 2 years afterwards, but in those 
days (mid 90s) I didn't really have much of an index system.
As I recall the trees were of much the same size as yours and Norway maple, 
but the care with which one extracts the metalwork is imperative. The trick 
is to smash off the outer part of the grille and try and crack the ring 
against the tree at the less deeply embedded (or nor embedded) parts, and 
then gently wiggle (hope this is not too technical for you) each part from 
the tree. (I do remember that with one of them, one half came away in one 
piece). I also recall that some cambium damage was inevitable, but frankly, 
if just in a few localised positions would still be less disruptive than 
grafts.
