There isn't much more to a probe like these
run of a mill x1/x10 low bandwidth probes electrically than it's transfer function (gain/phase), and you can see if that one looks good easily (i.e. fast square wave / compensation).
The mechanical and handling aspects are felt easily.
Given that this thing was probably made by some company that ceases to exist a few decades ago in the 70s or maybe 80s it's rather unlikely that you'll find any specs for it. Okay, compensation range might be interesting, but I mean, you'll see if it's sufficient for your scope or not when you try to compensate it.
So, I suggest, no more talking, try it out, see if it behaves and handles well... sometimes turning something on is much better than taking it apart, even if the taking apart part is just with words
