I thought Trefor quarry closed in the sixties? And if it's anything like the microgranite at Ty'n Tywyn you'd struggle to get a block much bigger than a fridge out of it. Shap might be a better bet, right on a motorway too.
Were the lines on the Shoreditch boulder chipped? I got the impression it was just left as is.
I don't think Frankland was interested in chipping. Have they been chipped since installation? I suspect he never imagined they would become so popular.
They weren’t chipped but have shot holes and large holes from where they had to drill to attach it to the crane, other than that I think the holds on it are either natural or a result of when it was blasted out of the quarry. It is quite fragile and lots of holds have broken off, especially when it started seeing more traffic during lockdown.
