John, yes, you are right. It is the same story I have heard many years ago.
The mismatch of the tkw 299g (official weight, see Met Bulletin) and 525g (see MetBase 7.2) is probably the result that some additional weight came out of Afghanistan after the first information was published into Met Bulletin 1960 (19).
If I count all K(A) together, which I have seen into Swiss universitary collections including my own large sample, which also came from a Swiss University plus additional 123g from USNM Washington plus additional 47g from Moscow Academy of Sci, than the result is a tkw of more than 450g. So the official tkw of 299g is definately wrong.

Continued from below: "The influence of the Soviets in the region was widespread, and Krinov was able to mount the efforts of the Diplomatic Corps in retrieving specimens of the fall. Through this the Kandahar meteorite was able to be classified as an L6, but the TKW is only a meager 525g. To date it is still the only meteorite from Afghanistan.
I have only been able to identify six (edit) specimens in private collections; those being in the collections of Mike Bandli, Peter Marmet, Jan and Wadi Woreczko, Blane Reed, Michael Farmer (edit), and formerly David L. Ribeca. Four other specimens are in museum collections. This 0.56g specimen comes to me from David L. Ribeca, and originates from a larger specimen in the collection of Peter Marmet. That specimen was cut from a mass at the Swiss Museum of Natural History."
Cheers!

Jarkko,
After I acquired a small fragment of Kandahar, I wrote a short history of the piece from available source, and shared it on the Meteorites facebook page. Here is a cut and paste of that.
"In November of 1959 a meteorite was seen to fall over the city of Kandahar, Afghanistan. By early 1960, word somehow had spread to Dr. Johannes Geiss of the University of Bern, Switzerland. Fresh meteorites were a rare commodity those days, and Dr. Geiss must have been eager to study such a specimen for he made the effort to write a letter to the Russian Astronomer and Geologist, Yevgeny Leonidovich (E.L.) Krinov. Krinov was known for his research on the Tunguska event, and was at the time a member of the Committee on Meteoritics at the Academy of Sciences, USSR.
During this era the USSR had dedicated considerable financial support (on the order of hundreds of millions of dollars) to Afghanistan for the construction of new infrastructure. The influence of the Soviets in the region |

Rare piece for sure. Would be great to know more about this fall. Seems there is not much information available, just checked the Meteoritical Bulletin. |
