Lots of side-car discussion on bluing and case hardening, real and faux.
To answer OP's question: Yes, it is trivial to strip the bluing off of any reproduction revolver. Simply fill a glass or plastic dish with plain old vinegar, and stick your blued revolver parts in there, completely submerged. Within minutes, the bluing will be gone.
I personally am not a fan of "aging" or "antiquing" firearms. Seldom would anyone have done this to a firearm in period. When new, these firearms looked new - they did not look "aged" nor would anyone deliberately try and make them look so.
Now, there are some modern folks who would like a gun that looks 150 years old. I get that. But I still would not want to take a "like new" gun and make it look beat up.
Yet, I did it.
At one of the N-SSA Nationals I went to it was raining like in Noah's day. Evidently I put my Pietta 1860 Army up in it's case still damp, and when I removed it, the nice blue finish was freckled all to heck with rust.
So, I stripped it to give it an "aged" look, but only because the finish was already ruined.
