Somehow the hole didn't get cut, so I drilled it out. Note to self, drill it out before you glue the two halves together so that you can sand it down properly afterwards..
The long rectangular nameplate was supposed to be kept, but it seems like they threw it away with the rest of the cut outs! Doh! I made one up from a few layers of plasticard.
This had the added advantage that I could 'test' the idea of the wound tracker being made from acrylic as well, with the idea being that whatever colour the rest of the tracker was, the nameplate would be in opaque white acrylic so the player could write on it.
