Cooke for Carlisle
In February 1857 William Day of Carlisle who was headmaster at the Christchurch Boys School in Carlisle purchased a 4.25 inch portable equatorial telescope. As this was early 1857 it could still be a Thomas Cooke of York telescope rather than a Thomas Cooke & Sons of York, because it was around this time that the company changed its name.
He also in early 1858 purchased a smaller 3.5 inch telescope also from Cookes.
I did make some enquiries with the Border Astronomical Society back in 1995 to try to find out more about William Day but unfortunately nothing else was discovered.
If you know differently I can add the information to the Cooke data base.
