The one tin National has that is unique to them is the little "half" tin as I refer to it. I cannot determine if these were meant as pre-packaged tins or given along with the purchase of bulbs bought out of boxed case bulbs. I have one rarity with a label on the bottom that has made me raise this question. There are 3 versions of these tins which in the beginning I never caught onto the differences of but they are all individual.
