If it's a 1959,it can't be a Musicmaster II. The Musicmaster II version wasn't introduced until 1964. If it's a 59, it should only say "Musicmaster" on the headstock, not "Music Master II". Where are you getting the date info from? Have to know the correct date first. Just so there's no confusion,here's some pics of the two versions.
Musicmaster
Musicmaster II
