I have a Hawes 1860 Army that looks brand new. When they bored the barrel they didn't remove the circular boring grooves the whole length of the barrel before rifling it. So you have boring marks with rifling over them. Amazing how these get through inspection and quality control. The other parts are worth what I paid for it but kept it as is as a curiosity. Must have been the last one off the line on Friday and they were in a hurry to get home.
Tool marks across the tops of the lands are evidence that the barrel was reamed with a dull or damaged reamer, or without sufficient lubrication. Most makers don't bother to lap or smooth the original reamed bore before rifling, but really rough lands are evidence of poor quality control. Tool marks in the grooves can be longitudinal, due to the condition of the rifling cutter (or maintenance and/or operation issues), or, if they appear across the groove bottom, due to chatter of a dull cutter or one operated incorrectly. Neither condition should be present in a correctly made barrel - but, as discussed, quality control appears to be a sometime thing in many Italian reproduction firearms.
