[meteorite-list] Am I missing something here?

[Zelimir Gabelica]

Yes, thanks to Jeff for these clearings and examples for LL's.
Note that, in contrast to the Met Bull on line, in the new edition of 
"Meteorites from A to Z", the LL petrological types as given by Jeff are 
correctly mantioned, except for Bishunpur, which remained LL3.1 (but 
LL1.15  in Met. Bull.).

Alex, 2 little sisters of your Krymka, a complete slice of 17.4 grams and 
another of 28.2 g will be exhibited next week-end in Ensisheim (theme: 
meteorites from Russia and Eastern Europe).

More news on Ensisheim (latest info) to follow later today.

Best to all,

Zelimir
