Ayeee good question.
Im alvays a little surprized how Moroccans can recognize that chondrite is
E-type. From my 12 years collecting/dealing practice, I can recognize most
of types by eye (so Moroccans also can do this ofcourse), except
E-chondrites. For me they are typical OC impossible to recognize without lab
tests, especially when specimen is complete. Thats why I never bought
possible e-type chondrite from Morocco.

Anyone have any hints for us ? :D
