Up, Down, What’s the difference?

My recent post about setting up to cast 18 point display type got up and down mixed up. When casting 18 point on an English mould with an American display mat holder, the mat must be lowered, not raised as I had stated. There is a mat holder insert kit to accomplish this, but it is the one insert kit that I don’t have.

I have added corrections and an addendum to the original post explaining the oopsie.
