Lost episodes
This is a tough series to peg in regards to timeline. It's listed in many places (including IMDb) as being a 1951 series but virtually every episode guide lists the first episode as having been telecast in April of 1952.
Similarly,the original run is cited in many sources as ending in 1959 with 72 total episodes but the Sky King Fan Club website http://www.angelfire.com/mi/freeper/ has the series continuing in first run until 1962 with 64 episodes that have supposedly been lost in a vault fire.
Anyone know what the real deal is?
