Perhaps this is the exception that proves the rule, but I've long
marveled at the distinctively different crust of the EL6 Hvittis
(witnessed fall - 10/21/1901); it's an articulated stubble which looks
much like the surface of the spherical sauropod eggshell from South
America. /d

From the exterior alone, I would have to agree that an E-chondrite is
almost indistinguishable from an O.C. The one E-chondrite I found in
Nevada looked like a very fresh O.C. -- presumably an H-chondrite

on the magnetic attraction. Even after cutting a type specimen for
analysis, I was convinced it was a very equilibrated H-chondrite. But
it turned out to be a weathered (W4) EL6 (Roach Dry Lake 030).
So the only anecdotal observational difference that I noted was that
the fusion crust was blacker than that of an ordinary chondrite.
