short walker, tall crutches (Britannia)

These are spares from my recent knee surgery: the two-wheel walker is rather too low for me – I'm 5'-9", and had to bend down to use this.

And the crutches are rather too tall – they fit a person from 5'-10" up to 6'-6". Also, the rubber grip is missing from the handholds.

Happy to dispose of these separately, to different-sized people!
