Broadcast in the United States on WOC Channel 6 at 4.30pm, on 14 June 1974 according to the photo and notes from my personal collection or 24 May 1974 if tv.com is correct.
I know the show was syndicated which would mean it would be broadcast on multiple channels but whether or not that would mean various dates I can't currently confirm.
