Very nice piece and a fun project gun!

I can tell you right now w/o the slightest doubt that those grips are genuine India Sambar Stag. And I would polish them up and fit them to your gorgeous Commercial model replacing the plastic grips.

Then I agree with most, keep it a snubby, the same length or shorter and solder on a proper original front sight and base. You can get them from old replaced bulged barrels. Get some nice handfilling wood carry grips and round the butt.

This all assuming the original barrel and cylinder checkout OK of course.
