Hello all, Can anybody tell me what "dog tags" (identity discs) are made out of. I know that most of them are made from aluminium, but during WWII some were made, in Australia at least, from what is referred to as "Pressed Fibre". They tend to be red-brown, thin, and the consistency of a very stiff cardboard. What is the fibre? Thanks in anticipation George Bailey Objects Conservator Australian War Memorial
