Knee scooter (Berkley)

Does anyone have a knee scooter from an old injury that's taking up space in their house that you'd be interested in lending or blessing us with?
My husband just had a bad accident spinning out on his ebike when there was a bunch of gravel in the road & severely injured his ankle. He has to wear this giant boot and isn't supposed to put any weight on it so he's using crutches and/or a cane but our house is pretty small so he's having trouble getting around with the crutches & sometimes tries to walk without assisting devices (which hurts and he isn't supposed to do). A knee scooter would solve this issue for him.
We do have a vehicle to meet you somewhere.
We don't have any extra money right now to buy one but we do have interesting things to trade if anyone is interested. Please and thank you
