Stumbled across this site yesterday, it provides an extensive list of all sorts of beer handpumps, clips etc.
But of real interest was the section detailing brewery taps, a great selection of pictures, and some ideas of places to visit in the summer… (this is from all around the UK not just Nottingham)

But wait, there’s more! A comprehensive page of hand pumps at railway stations.
