Not entirely unexpected tbh he's looked very poorly for a few years now. R.I.P Burt, another good guy gone!!
Seen him in the Smoky and the Bandit movies and a movie we have called Driven, where he was in a wheel chair. In Gunsmoke he played the Half-Breed (White/Indian), Quint. His family did state that he'd been in poor health and was already in the hospital when he had the heart attack. What an actor! RIP, Burt.
Note the horseshoe he is holding: it's size is of undue proportion, look at his hands. Only "throwing horseshoes" were made that large, and I doubt even the Clydesdales' hooves could be that big! But, no horse guy,. I could be wrong. Frank
