Without purse or script?

How many suitcases does a missionary need for his white shirts and ties and several changes of underwear? Apparently at least 3 HUGE HEAVY ones. We know since every six weeks they have transfers and we take them and their suitcases to the train. I thought missionaries were supposed to travel without purse or script. I guess these aren't purses so they are OK. Here Elder Beaumond is taking Elder Wright to Budapest...

and coming back with Elder Abram.

Now, in my day, we were only allowed 1 suitcase with less than 44 pounds. Now we travel with just a backpack and a small carry-on. We've got to retrain the younger generation!
