Superman on radio

[nighttrain]

Hi,

I'm trying to find the dates (year, at least) of four Superman radio episodes. They were broadcast sometime between 1945-9/

If anyone knows, I'd appreciate your emailing me at nighttrain@nyc.rr.com.

[1] Superman visits underwater city (Atlantis?).

[2] Superman hit by atom bomb.

[3] Superman finds bad guy by following trail of peanut shells.

[4] Superman premium of records (78's, I assume).

Many thanks,

Steve
