Hello everyone. Please, I would like you to help me date this badge. This was found near Cairo (Egypt) in the 50s. I have deduced from its patina that if it was lost during ww2, it would be newer and less rusty. So I think it comes from one of the ww1 Cairo camps. In that case, I would also like to know if the artillery troops from England remained with their original badges or changed them when they were assigned to the ANZAC divisions. Thanks in advance.
