hard bodied med/large suitcase with wheels for elderly lady (Whiston Cross L35)

My mum and her friend are going on a little trip to celebrate an 80th birthday - my mum was kindly gifted a suitcase but my mum's friend is in need of a medium or large one in nice condition - if possible the ones with 4 wheels so she can just move it round easily. I can collect and would be very grateful
