What Does GL Mean In This Old Recipe?

Q: I recently inherited an old handwritten cookbook from my Jewish grandma, originally from Poland. She has the sugar and flour measurements listed as GL. For example, the sponge cake recipe calls for 1 1/2 GL flour and 1 1/2 GL sugar.

Does anyone know what this stands for?

Editor: I’m also stumped on what GL might stand for. Readers, have any of you seen this abbreviation before or know what it means?
