Beautiful. Nice wood too. Yep, it's early manufacture. You can tell by the 2 screws on the upper tang just like the originals. The current crop only have 1 screw. I guess that was a cost cutting measure on uberti's part, and felt no need for it. That's just my guess.
You done good. Congratulations on this extraordinary find. Yea, if it was mine, I'd keep it shiny and bright too.
