Thanks for the comments, @jca and @Coloma. When I didn’t get any feedback on my question yesterday I wondered if I were the only one who remembered him.
I became a Milner fan during his “Route 66” years (what teen boy at that time didn’t want to tool around the country in a Corvette!), and remained one through his decades of TV and movie appearances. He wasn’t a GREAT actor but certainly a good one, and yes, so handsome and youthful for so many years.
