British anodised badges: help needed

[kingsley]

Rather a strange request.
I have been collecting 1899-1945 British badges for many years and can claim a reasonable knowledge of them. About 30 years ago I bought a large assorted collection which included a tin of anodised badges, and they have stayed in the tin ever since, plus whatever others fell from the sky. I know nothing about them. Which are rare? Which were disbanded and when etc etc
Can anyone can direct me to a link which shows sets of anodised badges? It might be time to empty the tin and put them on a card. I could even leave space for missing ones in case they also fall from the sky in the next 30 years!
Thanks.
