I was more or less asking if there was any NEW evidence to continue to support the mercurian hypothesis, i thought it had been actually rulled out instead of simply left as an unlikely suspect. Ie David Weirs web site entry for nwa 011 said that Mn-Cr isotopse data from boddanovsky et al actually rulled out mercury as the parent body....

There has been speculation that NWA 011 may be from either Mercury or Venus.
But it is just speculation, and it is most than likely to be from an
asteroid.

Quoting from the link you just provided:
"The material from which NWA 011 originated may have been like some CH or CB chondrites, members of the CR chondrite clan, which are all related through oxygen isotopic compositions. The NWA 011 parent body is probably of asteroidal origin, possibly the basaltic asteroid 1459 Magnya."
