BASF LH-R/SPR 50 any good?

[WarmJetGuitar]

Hey there!
Any of you people have experience with some old formulation BASF tape? It's called either LH-R, SPR50 or both?
I found it as half inch for a ridicously low price. I don't mind if it is a +3 tape, saturation has its uses for certain kinds of music. What I do mind if it's SSS, is lacking high frequency or something along these lines. I suppose the format rules out it being voice logging tape?
Never tried a shitty BASF product but you never know.
Could hardly find any info on this tape.

Looks like it should be. Apparently it's studio mastering tape:

I've not heard that they had shedding problems. In fact, someone claimed that they stubbornly avoided the binder which turned out to be bad because AGFA had the patent and BASF didn't want to pay licensing fees to their rival.

JP, you're like a human encloypedia regarding these things - thanks comrade
What does all these things with "remanent sat. flux" and nwb mean? It's related to how you calibrate a machine right? Can these be translated to terms as +3, 6+, etc. as for bias? Anything a not-as-technically minded guy as I can understand?

I don't know what 'remnant saturation flux' is about, but nWb/m is nanoWebers per metre and AFAIK, an amount of magnetism as recorded on the tape. And yes... 0 is 185 nWb/m, +3 is 250, +6 is 370 and +9 is 520, figures you may have seen bandied around on the forum.

Since the numbers quoted are much bigger I wonder if it's the absolute maximum values the tape can absorb? That's just a guess, though.
