Looking For An Apple Crate

Instead of just strapping a bag full of food and wine to the front of my bike I would really like to find an old apple crate, something akin to this:


While the one pictured is the actual rack, I would like one that I could just attach to my Gamoh rack. The idea partially comes from the Cetma Cargo Bike.


The box is removable and there is still a platform. Also, the apple crate needs to be free or very very cheap because I'm seriously considering purchasing the Cetma.
