Those these are all of the same general pattern, they are not identical and all show small variations. Like many of this type the tagane-ato punch marks around the nakago-ana were probably added in the workshop when manufactured, to give the impression that they had been mounted but are usually just cosmetic - some would have later been mounted but not many.

Another type that depicts the same scene are usually described as Hamano - the Hamano ones are identical and must have been mass produced but are often not finished to the same standards. I would much rather the hand finished Soten signed type! These can be expenive rubbish.
