From the pictures the parts appear to be gold plated, very shinny & bright. I agree some will appreciate all the accents, most won't.
If you want the parts to return it to original I most likely can get you there. We can discuss PM.
The 30C Blackhawk really needs to be looked at as a "HOT 32", they are fun to shoot and the recoil is minimal.
I personally do like Brass Grip Frames, However after I complete fittment, finish to a near perfect high polish, I then let time do it's thing. Brass dies down, and the patina over time gets better & better, "Bronze" IMO, my preferences,
This NM 30 carbine was left to me, bone stock, I didn't care for the alloy grip frame, too small for a 7.5" barrel and the 30C is a HEAVY gun.
NM Brass Super Dragoon GF, Hunter Grips, & Super Hammer that I acquired that was slightly messed up, so I cleaned up the "drop" w/ a slight re-shape. I think the size of the Grip Frame matches up overall better than the original, I also prefer the lower & wide Super Hammer, again my preferences.
I wanted to keep the modifications "Ruger", so that 50+ years from now, when I'm long gone, some young new Ruger enthusiast will log onto the Ruger Forum and ask; Was this a gun built by Ruger?
