When I blog, where at all possible, I will continue to quote the sources of my information and cite them accurately on this page. Similarly, when pictures are added I will credit the links, when and where possible. If there are any sources not quoted, will you, my readers, please confirm this by email?
Kind Regards
Tony William Powell
