The only marks I’ve seen in my long history of looking at metal that are similar to the little wave marks are from electric grinders, if the tool has a threaded shaft for attaching the abrasive discs, and the threads protrude from the nut affixing the disc (which they usually do), then if the worker touches the work piece with the shaft of the tool (which they occasionally do) it will skip along the surface and leave impressions of the first couple threads in a regular pattern like that.

Seems a good possible explaination Jeff, especially the 'thread' markings
However, what doesn't make sense is why they are there. If this is a 'high end' fake, why would the evidence be left for all to see. All the marks seem to have occured after the 'hammer shaping' ....which I would assume would have been the last manufacturing process. So can it be assumed these marks happened later...and if so, was there a purpose....testing of the bronze
If these heads were artifically 'patinated' , the sort of chemicals used such as ammonia, urea etc to 'induce' this, would not require tongs or mole grips to place the item in solution. A number of Chinese fakers bury them in urine soaked, highly mineralised soil.
