Thank you for your interest in this quality pair of vintage panniers . One of the bags does not feature the top hooks to hang from a rack. It does not appear as though they were ever installed. I do not know how to connect the bag with the missing hooks to a rack. The pannier with hooks has lost elasticity in its lower rack engagement strap as photographed. The zippers, buckles and snap fasteners are in good shape. The fabric is sun faded. Each side features small internal zipper pocket.
The dimensions are:
15” tall and 3x10” at the top tapered to 3x 6” at the base.
