From Catalogue 63 of Castle Bookshop, Llandyssil, Montgomery (tel 01686 668484):
 
36.  Scarfe H. M. 'Aquae Solis, or notices of Roman Bath', London 1864 at £75.00.
 
40. 'A Guide to all the Watering and Sea-Bathing Places . . .', by the editor of the Picture of London, 'improved edition', London, 1815 at £125.
 
49. Adair, J., 'The Pilgrims' Way: Shrines and Saints in Britain and Ireland' (Thames and Hudson, 1978) at £14.50.
 
Plus loads of archaeology, prehistory, Roman, Anglo-Saxon, medieval, landscape history (including some aerial photography), architecture, inc. church, local history. I think I saw the report on the excavation of Coventina's Well, late 19th C, but I can't now find it. Perhaps I've finally flipped.
