Jungle Mystery

Although various sources claim that this serial is "lost", I clearly remember watching all 12 episodes on Sunday morning television, c. 1981, on the Halifax, Nova Scotia, affiliate of CBC. The serials they showed might have belonged to a local collector, so there might be a copy out there somewhere. Even as a kid, I realized that it was a pretty creaky story and the portrayal of black Africans was pathetic even by 1930s standards. What also stuck in my head at the time was that the young hot-headed nephew (?) in the story was Noah Beery,Jr, who, c. 1981, was still popular as Jim Rockford's father in the Rockford Files.
