Indeed. And I did exactly as this report suggests and carried out my own independent analysis, regardless of whether CRU did or didn't make their data/software available.
Is it safe to assume from your resulting graph that "warming" in England has been fairly steady from 1750 and the mean temperature actually rose more dramatically from 1750-1850 than in modern times?
Not really. Because of the high variance it's difficult to make claims of that sort. You have to bear in mind that prior to the late 19th century Stevenson screens were not in use, and thermometers themselves were less accurate. Also it's pretty clear that there are systematic biases in the data, meaning that WMO stations on average move closer to the equator over time. I havn't checked whether this bias exists for the UK data, but it does for the overall data set.

The station data and temperature data were already out there in the public domain.
