Old Recipe Ingredient: Pastry Stick

I took my Mom to the used bookstore today. While we were there, she got an old DAR cookbook that had a recipe by one of her first cousins. The recipe called for a "pastry stick." I asked what that was. She said that they used to sell them and that they looked a lot like butter sticks. Mom had never used one. I decided to try to search the Internet to see if I could find what they were. I can find recipes for puff pastry sticks. I can find pastries that have a filling and are stick-shaped that are called pastry sticks, but I can find nothing butter-like or a dough that is to be shaped like a pastry that is called it (at least so far). What would be used instead of a pastry stick in the modern kitchen? Does anyone remember these old pastry sticks?
