Hi Listees!

I'd like some opinions on a meteorite I cut open yesterday. It's an
oddball I've had in my box of NWA for some time - awaiting a date with
the saw. It exhibits a very low magnetism and it has a grey matrix
almost entirely devoid of chondrules - although there does appear to
be some remnant chondrule structures. I'm hoping it might be some
kind of achondrite, but the magnetism mostly rules that out. Is it
some uncommon type like an L7? Or is it just something common that I
have not seen before?

The exterior has a wind polished desert varnish on it and there
doesn't appear to be any fusion crust to speak of - although there are
a few scattered tiny patches of black on it. The stone weighs 16
grams. I only made 2 cuts - I cut one corner off to expose the matrix
(endcut) and I made one thin slice. The rest of the stone is intact.

Here are some photo links -

Any opinions are welcomed.
