I think I have an old cassette tape of two “Frank Merriwell” shows, but I don’t remember much about them. There was a Merriwell movie serial back in the 1930s, from Universal. Seemed to be a sort of ‘collegiate/sports-oriented’ hero, who got into various scrapes. Always assumed the character came from line of vintage juvenile books, akin to “Bomba the Jungle Boy” and such. But I never really knew for sure.
Thanks for the info and insight. Will see if there is substance there...
