I had noticed that, but I can't tell if it's the name of the engraver, a company, or a description. The second word may be Brescia, which is the region where Uberti is located.
It's possible a guy bought a rifle from Taylor's and had a lower cost engraver attempt to match a pattern offered by the factory. I think I was quoted something less than $2,000 for that pattern via the factory.
I will add the machining on that '66 is better than some I've seen locally. For one thing, all the screw head recesses in the receiver are round, no ovals.
If I knew I would get machining, engraving, and wood like that shown on the factory site, I'd be happy to pay for a custom rifle from them. As it is, I'm looking at the Japanese "Winchesters" instead. I'll keep an eye on the '66 at local stores, and if I see a good receiver, I may buy the rifle as a donor for a custom build.
