Most Colt stars remain pretty anonymous and attempts to find out what they are doing now are pointless. Notable exceptions are Steve Kelso and Carl Hardwick (Rusty Jeffers). However, I got a bee in my bonnet about Mr Hawkwood the other day and was surprised to find out that Byron has been hiding in plain sight. His real name is Duke Valenti and he's been in real movies and ads that Ive actually seen. A little Facebook stalking and I even found a cute picture of him as a teen. As he has aged the resemblance to his handlebar mustached alter ego has faded a bit, but look at his "Tarzan" black and white photo below (apparently from a Variety ad where he was hoping to land a role with Bo Derek as Tarzan) then his bouncer ad and you can see its the same guy. The you tube clips are worth watching. He is nearly always cast a biker. Still got them muscles....
BTW apparently he was Mr Hawaii 1978--if any one can find a pic of that please send it in!
