Thanks Bill. There are certainly a number of other inserts, and figuring out how they fit into the chronology is a little confusing. I believe this insert is correct however not sure what period its from. I appologise for redirecting this thread from Mark 1,2,3. I was just comparing my insert to a similar one you posted under "There are a few other variations which I have not really classified as I am actually not completely sure".
