Mervyn, Thanks for asking. I'm a bit of a "Heinz 57" really. British father and German-Russian mother; born in what was the Gold Coast Colony (now Ghana, West Africa). Have lived in many places. Was a police officer in Africa, England and USA (now retired). Have a large police insignia collection from the UK. Also smaller collections from the old Colonies and Dominions. My USA police collection is mainly based only on personal experience. In addition, many books and original British Parliamentary Reports, Acts and so on. Many would describe my collecting and interest in British policing history as bordering on obsession (for one, just ask my wife)! Hope it is okay to mention I have written a very large and extensively illustrated book entitled "Police Reference: England and Wales (plus the Channel Islands and the Isle of Man)" (ISBN 978-0-9858978-0-2). For those who may be interested, there is an informational website about it at https://sites.google.com/site/policereference/ Not an admirer of self promotion, but mention of my book seems in context here. Best wishes, Peter.
