If anyone has full kinescope recordings, early videotape transfers, or digitized copies of these broadcasts, I’d be extremely grateful.

Full episodes only — no partials.

Google Drive, MEGA, Dropbox, or any simple file‑share works great.

Thank you very much for taking the time to check your archives.
