First and foremost to Peter Smith of Sudbury, who so generously offered his collaboration and allowed me to scan his fine collection of old Smiths Catalogues.
Then my thanks and acknowledgments go to the Library of the BHI, to Brian Thatcher and Greg Fincham in New Zealand, Mark Willis in Australia, Henry Weiland in the USA, John Hubert, Dan Godley, Mansel Jones, John Abbott, John Galvin, Mike Bundock, Derek Frampton and Peter Mitchell in the UK and to many others for help in sourcing pictures, advertisements etc.
I also wish to express my appreciation to Smiths Group plc, who through Mr Jonathan Flint very generously gave permission for the use of material from their catalogues, advertisements and publications.
