Sir Richard Gresham’s steward accounted for the shipment of about 100 pigs of lead to Hull via Boroughbridge and York. Including payment for mining and washing ore at Greenhow Moor and the smelting of 22 pigs at a bole hill. One fother of lead “of Bolton Moor” was bought from Thomas Proctor, who was about this time the sub-lessee of the Crown’s disputed interest in the Mungo Gill mine.
