Anyone hear of Tom Laughlin from te Billy Jack movies?

He seemed to have disappeared about 1978 or so. I happen to own the 30/30 Winchester rifle used in the 3 Billy Jack movies with the saddle scabbard and BJ initials. Not a prop gun either. The real thing and manufactured in 1954. Tom Laughlin was pretty good in martial arts too. Used the Tai Chi Sholin style. Never met him. I purchased the rifle from a guy in the studio props department. One of the more valuable guns in my collection.
