we're gettin there... I find that carrying your gun in a soppin wet leather holster makes for a great blueing remover...... The cylinder and barrel all happened in one day of heavy rain..... It is NOT holster wear.... !!!!
I think I'd come up with a steel ERH and strip the bluing, then "age" it a little with water to match the rest of the gun. MIght not be "original" but it would sure look good. JMHO
I did pull the ERH and soaked it in bleach. Came out well and matches the grip frame look. I do think a steel aged housing would be even better but I have not found one yet.
Natural "wear" on a gun adds tons to character! A few years back I bought an old flatgate from Scott in that same condition. Shoots perfect and no fear of skinnin' up the finish!
The center fire single actions with 4 5/8 barrels are my favorites.
