Coping Stones (Duddingston EH15)

We’re looking for 7 metres of traditional apex (twice weathered) coping stones to put on top of a single skin party wall that has exposed bricks on one side and has been harled on the other. Width 140-170mm. Ideally we’d like to reuse some old stones grey/buff with a weathered texture, but we’d consider new ones too. Happy to collect.
