Collection includes 2 episodes donated to Dadsotr which are unidentified by OTTER. The Side 1 of the cassette hints to close proximity to Halloween.  Side 2 is the next episode which indicates Halloween had just occurred. No date in Otter logs has an episode in any year that is close enough to Halloween to match these clues.  Both episodes on these rare recordings start with Hopalong readings so only a hint to an approximate year, 1951 or 1952 is possible.
