Taking the minor road east off the A485 I parked up on the grass verge opposite the field the O/S map showed the stones to be.
I hopped over the (brand new) barbed wire fence and made my way through the field to the back of the house where one of the stones lay.
The large quartz stone was easy to spot from the field, in the middle of the garden, approximately 1 metre x 2 metres.
