I think, what we have to bear in mind, is the age of the photo. It looks to me to be 1950's/60's. In the past fifty years tracks will have widened, narrowed, disappeared or appeared where they weren't back then ( if you get what I mean
). Also a bit of erosion could have have taken place to this type of rock which doesn't look typically 'tor-like' - it looks to be more angular and has considerable grass covering well up it's height.
Wherever it is, it's a popular tourist location with easy access from the road (going by the clothing).
With this in mind it may not be Devon at all. I've been looking at photos of the Cow and Calf rocks at Ilkley and, yes, when all is taken into account, it could be there.
But if it is Devon, how about - and I know it's a long shot - Brent Tor ie the large rock to the west of the rock that St.Michaels church stands on. You have to pass round it, in the same orientation as the rock in the photo, to join the path up to the church.The narrow track to the left is not used much now as there's a farm track providing easier walking. I believe the farm track is a more recent development. Also the rock material is more like that in the photo.
The picture I've attached is taken from too far along the track heading north and a better comparison would be achieved from maybe twenty yards south (to the right of shot). From there, the top looks flatter.
To be honest, it could be anywhere..........
