Okay, here's the result of some research:
Gene Autry, Bob Reynolds, Lloyd Sigmon and Signal Oil all had money in Golden West Broadcasters.
Reynolds and Sigmon were at KMPC (Reynolds since 1938, Sigmon since 1942) under the previous owner when he died in 1951. They partnered with Autry and bought the station in 1952 for $800,000. That was the beginning of GWB. All the other stations (KSFO, KEX, KVI, KTLA) and the Los Angeles Angels came later.
Signal Oil bought a 49.9% stake in GWB in 1968. Not only did Autry get investment money, but the deal had Signal paying Autry $250,000 a year for the option to buy the rest of GWB upon Gene's death.
Ina's will required that Gene sell off her portion of the community property within 5 years of her death and put that money in the Autry Foundation. Somehow, KMPC was exempt.
Autry sold KTLA, and used his share of the proceeds to buy Signal Oil out from the rest of GWB. The other stations followed, except KMPC, which he held until the late 90s. There were even some post-Ina station acquisitions (KUTE-FM), but nothing ever on the scale of the stations GWB once owned. And by the early 90s, it was turning into estate planning for Gene.
Jerry, I don't know if John Reynolds was related to Bob or not.
