Over the years, the Roll Stamps on Italian Guns has gone through lots of changes. The Roll Stamps are even changed in the midst of current production runs. The differences in the Roll Stamps are meaningless. They are just listed as being "different." Different production "Runs" can also contain entirely different serial number ranges.
When USFA went belly up, suddenly USFA guns became instantly "Collectors" although those with Uberti parts, not so much. I may not "get out" enough these days but I don't know of anyone "collecting" Cimarron or Uberti guns. None of your cited "strangeness" would have any effect on value or price (that I know of).
