Eyup Mr Stu,
I'd have thought not, as the whole arrow sharpening thing obviously puts them well out of the usual timeframe for the C&R style rock art. But then they could be pre-roman iron age things, mebbe.
There's also some speculation that they may not have started off as arrow sharpeners. There's a prehistorically-prehistoric portable up in Dumfries & Galloway that has marks that look like they were made in the same way, but radiating out from a cup.
