Fleetwood "The Golden Olden Days Of Radio" full boxed set

I purchased this full set of 8 track old radio shows in an auction this weekend. I absolutely love the old radio shows and could not resist bidding for this set. The set is complete and in very good condition, I've listened to two of the six shows and they were complete radio shows. I tried to do some research on this set but was surprised to find nothing at all on this set online. I was hoping someone on this forum could tell me something about this 8 track set or even point me in the direction of where I can research myself. The forum has in the past been very helpful and was hoping they would help shine a light again.
