Someone looking for a 1972 Concentration episode

[WarioBarker]

Got this message on my talk page at the Game Shows Wiki shortly after Midnight today:

Hi Daniel, I am searching for a particular episode of "Concentration". A friend of mine asked me to try and find the episode that she appeared on and won. I believe it was in 1972 and it was the 14th anniversary. The contestants were all 14 years old and did not have the option of returning as a champion. My friend believes it was taped in August of 1972 but isn't absolutely sure. If you could give me any information on how to get a copy of that show for her, I would greatly appreciate it. I have been searching to no avail. I do not even know who I could contact to see who would have this archived episode. Thank you for your time.

Anybody have any suggestions or leads I could give to her? I know this place helped out someone else who was looking for a 1958 episode back in 2007, hence why I'm asking here.

(From what little I know, the 14th Anniversary was a special week from August 25-29.)

Does Norm Blumenthal still comment on here? Maybe you could get in contact with him to see if he would know whether or not that episode was saved.

Theoretically, a huge number of Concentration episodes were among a massive donation that NBC made to the Library of Congress decades ago.  However, I've never heard of a single episode of that stash having made its way to the public.

Isn't that the episode where they shows the back of the board and how it worked? I can't imagine why that episode would be scrapped.
