I found two books last night that i purchased back in 1981 when first got my Cougar II. "Doctor your own compound bow" and "Sensabout Bow Tuning". I googled the author and just read this heartwarming story.
I checked on Ebay and someone is trying to sell the book for $187 dollars!
The book is like reading a archery history book. There are pictures of all the bows of the day. For Martin he has the M-4 Cougar, the original 4 wheeler. He also has the Kam-Act MK2.
Anyway, I really liked the story about him. He is still alive and winning tournaments at the age of 92!
