Hi Danny, In response to collectiing Canadian Cap Badges, You did not indicate what period you would be interested in. A) Canadian Militia Badges Pre 1914. B) First World War. C) Canadian Badges 1920-1950. D) Second World War. E) Canadian Army 1953 - 1973. Let me know what period would be of interest to you, and I will be able to give you a few book titles. Concerning restrikes, all I can say is buyer beware, as there are some very good fakes out there. Cheers Woodbine
