If you go through the threads on the picture/photo forum, there are a couple started by Bruce Day that have what I believe to be original cases with both. One of them is a C grade the other I believe is a D...anyway, they are both original cases I believe and neither of them have a parker label of any kind.

The below link has a pick of an old case in it with a label, but I don't know if the label is original or not, you would have to check with Mr. Day.
