16 Vintage Reel to Reel Tape holders with Reels and Tapes

Description

This listing is for a lot of 16 gray plastic 7 inch reel to reel tape holders.
15 of the holders have reels with tape in them, one is empty.
The holders open by turning the two halves in opposite directions.
Of the 16 holders, 4 have all four of the tabs for holding the halves of the together.
11 of the holders have 1 broken tab, but the holder still closes securely.
1 of the holders has 2 broken tabs, it still closes but not as well as the others.
The tapes mostly contain recordings of German music.
They were recorded from the radio or LP's on a well worn Sony TC-630 so the sound quality isn't generally that great but the poor audio quality doesn't necessarily mean the tapes themselves are in poor condition.
The tapes were purchased probably from the 1970's up to the early l980's.
I don't know what the lifespan of a tape is so I don't know if they are still usable for recording or not.
This listing is mostly for the tape reels and cases. If the tapes can still be recorded on, that is a bonus!
THE TAPES ARE BEING SOLD AS-IS. I MAKE NO CLAIMS WHETHER THEY ARE USABLE FOR NEW RECORDINGS.
The condition of the tape itself seems OK. The first foot or so of some of the tapes is beat up but that can just be trimmed.
As for the reels themselves, 6 are 3M/Scotch brand, 3 are Ampex, and 6 are generic.
The brand of the reel probably doesn't indicate the brand of the tape that they hold.
