However, this is (un-confirmed) literature information.=20 =20 For basic meteorite data like type classifications or TKWs, I usually = take the most recent information published.

When the = label came in, I noticed that the TKW on the label was 260 kilos. I = then checked Meteorites A-Z, which listed a TKW of 70+ kilos. The well = known dealer that I purchased the stone from also had a TKW of 70 kilo's = on his label. I then dropped Roman a note asking him where he got his = 260 kilo TKW from. He sent the attached description from the Met Base = that I have copied below. It is confusing in that it lists both 260 = kilo's, then 70 kilo's, and then 260 kilo's. I surmise that the = original fall find was 70 kilo's, and that it was adjusted upward at a = later time after more was found. Does anyone on the list have an answer = for this TKW question?
