3 wheel mobility walker (Waverton CH3)

Hi there, I am looking for a 3 wheel mobility walker with brakes and preferably a bag attached similar to photo for my father in law. Only a few months ago I gifted walking frames and one of these after my mother in law passed away and now my father in law has decided he is need of one !. If anyone has one in good working condition that is no longer required I would love to be considered for it. Thank you
