I'm looking for an old, sporterized Krag myself, as they have a long history in our family, here seen in 1935 at a picnic celebrating a successful Oregon Mulie hunt by a couple generations of ranch women.
Just an opinion, but I don't believe that light, stamped band matches the rifle very well in either construction or quality. Were this rifle one of mine, I'd dovetail in a storebought dovetail filler block to the underside of the barrel beneath the forestock, drilled and tapped for a swivel base.
Otherwise I'd spring for a milled band. These are 200-yard-max deer rifles, not thousand-yard target guns. Accuracy isn't a big issue.
