Last year I purchased a meteorite at a rock and mineral show a because it just looked a little different from most chondrites I have seen.? The seller did not know where it was found so I got the provisional name NOVA 010.? The exterior almost looked like an Iron or a Stony-Iron and it contained a lot of metal.? The metal also looked a little different - more globular then most H-chondrites I've seen.? I thought it might be a CH or an EH chondrite.? Well I got it classified and it turned out to be a "reduced H4" with numbers very similar to the "Burnwell" fall in KY., although it's even more reduced.

NOVA 010
?
W2 S3, olivine Fa 14.4 ?0.5 (n=7); low-Ca pyroxene Fs13.7 ?0.6, Wo0.6 ?0.3 (n=11)
?

Now here's Burnwell
?
W0(fall) S3, olivine Fa 15.8 ?0.2 (n=79); low-Ca pyroxene Fs13.4 ?0.7, Wo0.7 ?0.2 (n=98)
?

So you never know what you have until it gets classified.
