This was just one of a couple of examples I threw out to get a topic in circulation, and Jeff gave a more than adequate answer to the question. It seems that there's a certain responsibility on just about everyone involved to properly record the outcome of these events and that the science side is willing to do whatever they need to, within reason, to get the record straight so to speak (symbiotic, as it should be). Even the uncertain stories in the world of meteorites are part of the fun and mystique...

My information regarding TKW of the Chiang-Khan fall is from The primary finder and author of the web page cited by Martin Altmann: http://www.meteorite-oliver.com/About_Chiang_Khan/about_chiang_khan.html Of particular interest is the comment therein: " Nobody was able anymore to give precise indications as to the exact date of the event. Some 20 years ago it was, so they say, in the month of November, without doubt - that's what I was told in the villages of the strewn field. Whatever it was that happened then - one is led to presume a second meteorite fall on the same day or on the day after. According to recent research (isotope analysis), the two large specimens, which are in private Collection and in Chulalongkorn University, Bangkok, do not originate from the Chiang-Khan fall. They are believed to have been transported into Thailand from Laos. Two small pieces from Thailand were analyzed, one is H4 tending to H5; one was determined to be H5 in Japan, whereas the large pieces are H6. Most of all, the noble gas contents of the large specimens differ extremely from those of the Chiang-Khan pieces!" Please note that this is also weighted by the comments by Jeff Grossman Sent: Saturday, March 22, 2008 11:58 PM To: Meteorite-list at meteoritecentral.com Subject: Re: [meteorite-list] More on Chiang Khan "The Meteoritical Bulletin does publish announcements of new masses when they are significant. Submit the report to the editor. You will need good evidence that the additional mass is really part of same fall." Please also note that I have every reason to believe that both Bob Haag and Matt Morgan believe the piece in reference is part of the Chiang-Khan fall. However, this believe might be weighted against The above comments (and I acknowledge I could be wrong on this). I recognized your reference of source for purchase as "a dealer" was Almost certainly intended to protect me from any perception of shenanigans In this matter - and I thank you for your intent. However, I was fully aware Of all of the above comments and felt confident the major finder and the Meteoritical Bulletin were correct in their assessment of related falls, just as I am confident there is no intention to deceive, whatsoever, on the part of Bob Haag or Matt Morgan and that their belief in the authenticity of the stone mentioned is both sincere and reasonable. People will have to decide for themselves whom is correct and whom is in error. I sided with the primary finders and the Meteoritical Bulletin. I see no way to resolve this without individually typing the stone, but even that, like the Baygoria cluster.... Er... controversy .... will not be conclusive if this (other?) fall was also submitted and originally included as part of the Chiang-Khan fall, anyway - but the Meteoritical Bulletin does not see it as such.
