John Dehner played Kendall and while Dehner played a million Western parts in radio (in every other Gunsmoke episode and as Paladin in Have Gun Will Travel) I think he was best as Kendall. He was smart, sympathetic but also a moralist. Add the toughness in there and what you have is a bonafide Western hero - who didn't go around gunning people - in some ways he was like Matt Dillon or even Paladin. The only odd thing - he didn't own a horse and is almost never heard riding one!
As a gentleman, Kendall would often find himself the guest of a town's mayor or even a governor. He met up with some of the West's urban legends, such as Wild Bill Hickock and came really close to being with General Custer on that fateful day when Custer foolishly led his men into their last battle.
The sound quality of the series is superb. It sounds as good as anything out there; seems most of the Westerns of the late 1950's have this advantage over other series. I know some people refuse to listen to old radio that is even half-way fuzzy.
This series is one of the best out there.
