Knee scooter (Westhill AB32)

I know it is along shot but my friend has had a major operation to reconstruct her foot and is struggling getting about on crutches as her hands are starting to become painfully with them. We are hoping someone out there has a knee scooter as at 28 she is fully dependent on her disabled mum who is struggling a lot with trying to do everything as well as coping with her own disability. If anyone has it in there heart to help we would be truly appreciative.
