Hola, 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." Regards, Jason
