Harriet James will find a brief reference to the two Wadham sundials in Gunter's "Oxford Science" (volume 6 or volume 9, I think). Gunter mentions that one of the sundials is indicated in a plate by Loggan dated 1675. I doubt if this will be much help, but hope it may encourage somebody to do better.
