When the label ca= me in, I=20 noticed that the TKW on the label was 260 kilos. I then checked Meteorites=20 A-Z, which listed a TKW of 70+ kilos. The well known dealer that I purchase= d=20 the stone from also had a TKW of 70 kilo's on his label. I then dropped Rom= an=20 a note asking him where he got his 260 kilo TKW from. He sent the attached=20 description from the Met Base that I have copied below. It is confusing in=20= that=20 it lists both 260 kilo's, then 70 kilo's, and then 260 kilo's. I surmise=20 that the original fall find was 70 kilo's, and that it was adjusted upward a= t a=20 later time after more was found. Does anyone on the list have an answer for= =20 this TKW question?
