On the 20th December 1858 Dr Matthews from Tynemouth ordered a telescope of 4 inch aperture from Thomas Cooke & Sons York, plus a polished brass tube, a finder, four eyepieces, sun prism and dark glasses, two brass clamps for fixing to stand at a cost of £40. ( In 2023 that would be equal to £6,640)
