Hi ironbut!
label on reel sayed: "recorded in france", but on box: "manufactured by MAGTEC"
here a reel that i have:

.
and here that i found on ebay:

Boxes looks the same, labels on reels too, but reels are different.
I have one MAGTEC tape, and this tape have black plastic reel (like on second image).
Looks like in France use the same labels and box as in USA, and different reel design (clear or yellow plastic).
This is non dolby tape, so misstracking can be occurence only on master reading/creation stage.
My machine has tube preamp of my own design, and switchable EQ (HF 35,50,70,90 LF 0,3180), and i'm allready play this tape with 70us (IEC) EQ.
Okay, i'm try to buy this album on black reel (suppose that black reel - US recorded tape), and check quality of recording.
Thank you.
UPDATE:
I found this reel on ebay:

On label clearly described that this tape - MAGTEC tape.
