Here we go again,this my hardly smoked Dunhill Ring gran has developed a pretty noticeable crack in the shank, at first the crack was almost unnoticeable and even today the stem itself fits snugly in the mortise, now, My question is how shall I proceed with this sucker further,I was thinking of sterling silver banding,but could that be done without cutting the shank shorter,This shank has unbelievably thin walls.I shoulda bee lubricate it with Graphite.a Grateful Thank for Your kind advice,
