No insult intended, but are you familiar with the "BFR," made by Magnum Research? They predate the Taurus Judge by probably a decade, or more.
I believe Ruger and/or Pine Tree Castings had a hand in providing parts (frames, maybe?) for the early BFRs.
I think this could be a "Frankengun," with Ruger barrel, grip frame, etc. installed on the BFR frame.
The two-tone "pinto" look (to my eye, anyway) and barrel with the "Warning" might bolster that theory, too(?).
I shot a BFR in .45-70 in the early 2000s. It was all stainless, with a 10" barrel. What a hoot! I started thinking about it later, and decided the (factory) ammo must have been loaded to "Trapdoor" Springfield pressures. I'm not into the big boomers, but the rounds were still pretty pleasant to shoot. (5-lb. revolver might have tamed recoil a bit, too!) :mrgreen:
I look at the BFR in .45-70 like I do the Boss Hoss (Chevy V-8 powered) motorcycle- a novelty, or show-off item. A serious piece of machinery, but there are others that are likely more practical- and still offering serious power output!
