Gunkwazy,
Nice work! I have 'cleaned up' a police trade-in 65-3 with Flitz/Semichrome and elbow grease... even a 6" cotton buffer charged with red & white rouge on the gouges. My first 'attempt' was my 4.6" .45 Colt BHG Vaquero over a year ago. The 'bright' finish was easy to match after I had scratched the barrel up with 320-1,500 grit Si/C w/d paper... removing that Ruger paragraph. I highly reccomend it - a great improvement. I have removed it from all of my SS Rugers now, icluding Vaquero's, BH's, SBH, and RH. The satin finish of the SBH & RH was returned via some maroon ScotchBrite pads. I used a Porter Cable Profile Sander's concave-shaped sanding profile to follow the barrel's curve, but an old-fashioned felt chalkboard eraser works as well. I used WD-40 as a lube... it took hours, of course, but it is worth it. The beginning and end seem to have a deeper 'dot' than the rest of the roll-marked paragraph. Your .44 SRH will look a lot better...
My MG's, a .45 Colt 625 and 1 629, are laser-etched, I assume like your 629MG was. That would make them candidates... my roll-engraved ones would be too much trouble. The Si/C w/d paper can be had at any home-improvement store - an assortment of 320-1,000 is available at Wally World, even. I also like Ace hardware stores - usually very eager to special order goodies for you. I ordered a bottle of Flitz Metal Polish from my local Ace - it is green - like the case tumbler additive they make, unlike the pink-orange color of the previous (several years old) polish. Doesn't work as well, either. Hopefully, Semichrome hasn't changed. Try auto paint and body supply stores for the finer (1,500+) grit papaers.
