Wow, these comments really opened memory's vaults. Never saw Sword of Freedom, but The Vikings, Captain Gallant, Robin Hood, Circus Boy, and Sir Lancelot all ran on local stations when I was a boy. I was also a fan of Sky King (of course), Whirlybirds, Highway Patrol, Tales of the Texas Rangers, and Soldiers of Fortune.
A number of Soldiers of Fortune episodes are on YouTube in good quality prints, albeit without titles and credits. I was surprised to see the hero was John Russell, who later was the stone-faced hero of The Lawman.
A few years ago I bought a boxed collection of public-domain shows on DVD which included episodes of The Adventures of Long John Silver with Robert Newton. Apparently it was produced in Australia. Kind of sad, for Newton was obviously in pretty bad shape and he died a couple of years later.
UHF stations couldn't afford the good stuff, so they often ran older or obscure series, some of which were pretty good. I remember a British series called Zero One, with Nigel Patrick as an aviation investigator; another called Four Just Men, with Richard Conte, Dan Dailey, Jack Hawkins, and Vittorio de Sica (!). According to IMDB Honor Blackman appeared in half the episodes, but I don't remember her. Then there were a couple of old wheezes like Racket Squad and Boston Blackie.
Good times!
