Check out the last picture - there's a white chondrule clearly visible
in the upper right/center of the photo.
Also note the dark chondrule (large, but fuzzy) at the bottom edge of
the slice, a tad to the left of center.
I'd go with LL6; it has a few chondrules, and from what I understand,
the type seven designation is reserved for primitive achondrites. Of
course, it's hard to gauge L vs LL, but you did say that the magnetism
was "very low."
