That gun is not really pitted that bad.
The Spanish BillBoard marking on the right front side could be elliminated in a polish job with no worrys about having that re-engraved/marked AFAIK.
The rest of the gun can be polished out by hand w/o much trouble. Just time and patience. A very nice job can result.
It'll never be a money maker. That's why 'smiths rarely do the job as a restoration for a profit or take in the jobs at all unless you just want a spiffy buff and shine & hot blue..
DA Revolver polishing is very time consuming when a correct job is done. It doesn't matter who is doing the work outside of the Factory.
Even then it mostlikely won't fall into the Restoration Class of work. But that's not what is usually being sought in instances like this anyway.
Just a good clean, sharp polish.
A good project gun for the gunsmith type.
The Medallion is still deep and can be saved. The other lettering will need some help from an engraver to sharpen up to save it if you want to. Or have one of the Laser Wizards re-mark it.
The cylinder is the easiest to polish on a belt. The locking bolt channels need some very careful polishing out to get at the pitting in the bottom of them. Believe it or not , the Dremel with the correct shaped point is perfect of that. Be careful though!
Final finish,,Hot Blue, Rust Blue, Hard Chrome, Flashy Nickel,,the list is nearly endless.
The Hammer and to a lesser degree the (wide?) trigger look pretty eaten around the sharp corners by the pitting.
For a K frame it's much easier and cheaper to find and buy replacement(s) with decent finish than to strip and refinish (CCHarden) the originals.
Just the CCH will cost around $150 these days from the shops that advertise. Some won't even take in small jobs anymore.
There are some faux color alternatives. But then there is still the pitting to deal with, refinishing/polishing to elliminate it
Grips,,need some nice grips.
The project gun can get you in deep.!
Sometimes the 'Clean, Oil and Shoot' doesn't sound too bad after all.
Neither does 'Place it in the Trade Basket' after you are tired of it.
But some of us just can't stay away from a Project..!
I plead Guilty.
