I have a vintage sport wheelchair, a Kuschall 3000, that is approximately 35 – 40 years old. Other than one broken spoke, it is in good shape for its’ age. It could be used for basketball, tennis or pickleball although the addition of some type of anti-tipper would be helpful. I am hoping someone can use it since it has been sitting in my garage for years and I don’t want to just scrap it.
