They were the only company making early style lever guns thirty - forty years ago. If you see a yellow boy in a movie from the 1970's or 1980's, the credits probably say they were Uberti's. It was probably an Uberti used by Costner in the Buffalo hunt scene in Dances with Wolves. I have seen them in catalogues for years but never handled one. About thirty years ago, I bought a 92 Winchester clone (44-40) from Brazil. The action cycled a little rough at first, but got better with use.
Uberti has a good name for quality, and I have only heard bad things about Uberti once. I have two Uberti cap and ball revolvers and have no complaints.
You may want to check on one of the CASS or western shooting forums for comments.
I also don't know how they compare to the guns made currently by Henry in New Jersey, either in quality or price. I think Henry started making some lever guns in larger calibers.
