Add ham and pork slices, and cook each side until slightly browned then remove on a plate.
Butter cut sides of baguettes then place on the skillet, cut side down, for 2 minutes until lightly browned. Remove onto work surface.
Layer the baguettes with pork, ham, then cheese and pickles. Cut, break or fold the ham, pork and cheese so they fit.
Spread the other half with mustard then place on the sandwich.
Butter the bottom and top of the outside of the baguettes.
Heat skillet over medium high heat. Place the baguettes in the skillet, top with a sheet of baking paper then weigh it down with a heavy skillet or pot (use cans if necessary for extra weight so the sandwich gets compressed).
Cook for 3 minutes on each side, until dark golden brown and crispy, and the cheese is melted.
Let sandwiches stand 1 minute before cutting in half.
