Agisoft Metashape model : Cup marked stone, later re-used as a 'knockin' stane'. South of Loch Tay, near Killin. The whole surface seems to have come away from the stone to the left hand side of the prominent diagonal across its face. Unsurprising given its later use as a knocking stone. No doubt this removed a number of further cup marks - a number of 'fossil' cup marks can be made out along the line of the diagonal surface fracture.
