It is a 5-screw, so I'd be tempted to do more with it as a Model 28 than say a 3 screw. Not that there is going to be any difference in the final product as far as shooting and handling characteristics,,I just like the older stuff.

A caliber conversion to 44sp or 44-40 would probably be my first thought. Using a M24 bbl to keep the rapid taper or use a 29 bbl as a sleeve project to keep the orig bbl contour.
Probably cut down the length to 5" or some custom length, though the 3 1/2" N frame is beauty of a revolver.
Patridge front gold bead sight.

Polish the metal and engrave. Some small gold accents, just gold cylinder and bbl bands perhaps.
Finish in probably a coin/grey finish.
Tooth of the Pachyderm service or Magna style grips (my choice again).
Otherwise a nicely figured class act wood like French Walnut w/checkering. Nothing Blingy like those Zebra and Bubinga type wood grips.

It's a great gun to do a project on. But even if you do nothing more than clean it up some and just use it as-is,,it'll never let you down and still shoot just as well.
