Many, but perhaps not quite ALL of the Lucky Strike sponsored shows seem to be at
http://tobaccodocuments.org/atc/ Free registration seems to be required. There are pdf and tiff versions and all they tried to OCR but the text version didn't come out very well. Some sets have multiple versions. These are fascinating, and now with the scripts I can check how complete existing tapes are.
I haven't gone through the TV yet, (at first pass looks like TV from 1950 through June of 1959 are there, and many contracts/agreements too!).
Radio from 44-55 appears to be there except for
1950 - nov and dec
1953 - Sep - Dec
1946 - Apr - Jun
1952 - Sep - Dec
If anyone runs across the ones I can't locate, please let me know.
