Welcome to the forum, Charlie.
Those marks on the cylinder may be the results of someone bringing the hammer to half cock and then lowering it without bringing it to a full cock first. Probably pretty easy to fix with a matchstick and a bit of bluing.
As for the quality of your gun, USFA was well into their "Made in America" phase when they first brought out the Rodeo. However... There is a slight chance that they may have used some Uberti springs in some of the early Rodeos. I don't know this for a fact but I seem to recall hearing it substantiated that at one point the Uberti springs were used for a short period to keep up with production demands. Even if this was true, it is easy to change out the main and trigger/bolt springs. Personally, I wouldn't worry about it too much. The quality of your gun is on a par with current production.
Banjoman, who frequents this board, works for USFA. Maybe he can jump in and put some light on the subject.
