unusual Columbia tape...

[Gkar]

Has anyone seen Columbia tapes with a typical dull brown front side coating combined with a dull black backside coating?  Looks like the 406/407 tapes except the front side is dull brown, like all other tapes I have.  The reel is a bit different as well, typical grey color but just a single slot on each side, and minimalist label.  This one is Mahler's 9th with Walter, stereo disc M2S 676, thanks...

To me it appears to be backcoated, so someone probably replaced the tape with the sound of a CD. If you are lucky, of the same performance.

They had reels with a very small area for label, I have Miles Davis KOB issued in both that and the more conventional half moon label. Of all my 4 KOB tapes two have glue undone and one is missing the sticker entirely, the other still has it in the box stiff and dry of glue. Both of them are with the large half moon sticker, the last one is ok, and the one with the small sticker is also adhering well after all these years (knock on wood).
