It is pretty obvious that the first 3 practice plates were done earlier than the lion and the capper as my design and execution had very much improved (on the capper at least). The execution on the lion improved but the design was copied from a book. I do have a specific practice plate that I think would be somewhat eye opening and a useful aid but I can't find it. When I do I will post it up. For the record, I do not consider all of these designs to be period correct but rather, an analogous contemporary representation.
