Were those dramas live or filmed? There isn't much demand for kinescopes of early live TV dramas, because the video quality is so poor.
SUSPENSE is a perfect example. It was a wonderful radio series that lasted 20 years (to 1962). But as a live TV show from early 1949 to 1954, it looked very cheap. The full orchestrations on the radio show worked well, but to save even more money they had to use an organist for television and it just doesn't work.
