[meteorite-list] Meteorite unclassified

[Graham Ensor]

just an addition...an example.

Would people buy one of these Allende meteorites or similar from other
dealers pages which I think we are all pretty confident are Allende's...but
I'm pretty sure these were just fond in the same strewnfield and have not
been analysed to make sure.
