Reel to Reel, Air Force One, White House Recordings, 1970, 2 reels

Description

These tapes came from the estate of a retired Air Force One crew member. I was not able to ascertain his position.
-One of the tapes is a standard reel to reel with an insert indicating White House Communications Agency. Appears to have been used but I have no way of finding out what's on it. I don't have access to a player.
-The other tape is more of a mystery, I have never seen a tape like this. Labeled Cassette from United Control company. The sticker on it says AF-1, Pgm 03, #3, 9/3/70. I have no idea what kind of player this would be used on. I can find no examples of this type in my searches.
Even if they have no significant historical content, they are pretty interesting. Nixon was president at the time.
I have had them for awhile trying to figure out what to do with them but I am giving up and putting them up for auction.
