Acknowledgements

During the course of my research for the thesis upon which this paper is based I received help and support from many people for which I am deeply grateful. To all the museum staff, too numerous to mention individually, who made their collections available for study; to the staff of Stroud Library for their unstinting efforts to trace obscure books and articles; to my supervisor Dr. Peter Davey for advice, encouragement and hospitality; to Philip Graham for help and advice with computer scanning of photographic images; I offer my sincere thanks.

The following museums and individuals provided photographs and photocopies used to illustrate the text:-

Huntly House Museum, Edinburgh, Figure 87
Pontefract Museum, Figures 79b & 80
Peter Brears, Figure 82
Ron Dagnall, Figures 77, 78 & 79a
Peter Hammond, Figures 74, 75 & 76
Johan Hesemans, Figure 130
David Higgins, Figure 72
Adrian Oswald, Figure 71

Without these the section dealing with superstructures would be very thin indeed.

I must also thank Richard Savage, who proof read the penultimate draft, for his diligence and advice on signposting between sections. Finally my wife Jacqueline for her tolerance and support throughout.
