I recently bought a secondhand Raleigh Shopper for the sole purpose of nipping down to the shops. I rigged up a jury-rigged arrangement for carrying stuff on the rear rack but am wondering what basket is meant to attach to the little frame on the front? In the attached photo it's the lower frame which doesn't rotate with the wheel. (The bag at the top, fixed with the red strap is the Carradice bar bag from my nice 80s road bike.)
