I met John some few years ago when he bought a model from me that I was selling for another friend who had been admitted to a nursing home.
John was an astute friendly and inspirational man and I will always remember him for something he said........."if I can find a lake i'll sail it"
I hope sincerely John, that you've already found that big calm lake in the sky, and enjoy your eternal fun..........you deserve it.
RIP, and my prayers go to you and your family at this sad time of reflection.
