Dub was a fantastic character actor. Besides westerns, he had a hilarious supporting role in "You Can't Take it With You" and I even noticed him in "Mr. Smith Goes to Washington." Buck had a print of himself with his dad (I think they were in their “Conagher” costumes). I commented on the fact that I appreciated him too and Buck said something like, "Now he was a real star." I kick myself for not buying the print from Buck. I know I can order it, but it would have been cooler to buy it from him directly.
"Dub" was, of course, short for "W", which was, in turn, short for "Walter", both his and Bucks given Christian names.
