My father was an inpatient at Stoke Mandeville for quite a few years in the late forties and early fifties, and along with the usual therapeutic activities designated suitable for paraplegics, he became very good at Archery, even though he had never touched a bow in his life before that time, being a University rower and golfer.
I can't remember him saying anything about a shooting club, but even if there were one in existence at the time, he wouldn't have belonged to it as he was extremely anti gun. I was never allowed an air pistol at home, and even toy guns as gifts were discouraged.
I remember he had nothing but praise for the therapists at Stoke, apart from frequent references to their only skill requirement being a degree in Masochism, or words to that effect , who helped him immeasurably, and it is very sad to hear of the decline in the standard of shooting facilities offered.
I wonder if they still practice Archery as well.
