Hi Martin, Mike, and all,

I've always liked Bogou too, probably because of the photo below from Al Lang's site.? Unfortunately I don't have a specimen :-(

http://www.nyrockman.com/museum/bogou-8.htm

Al's?etched part slice has a very cool heat-affected rim on it.? Of course the question?concernimg your specimens is:? Do they also have a heat-affected rim?? ?and
do you a). refinish and etch it to see, or b). leave as is.

(Just thought I'd add another variable to the equation)

Cheers,

Frank

Hello Martin and All,

http://www.meteorite-times.com/Back_Links/2009/august/Accretion_Desk.htm

It?s nice to see a witnessed iron on the Accretion Desk this month. It is quite easy to forget that witnessed iron falls are incredibly rare. In fact, according to the MetBull database, witnessed HED?s are more abundant than irons at ~69 witnessed HED achondrites to ~49 witnessed irons. Even at that number, iron falls are so highly prized by museums and institutions, that you are lucky to find anything outside of Sikote-Alin, Udei Station, or the occasional Boguslavka or Braunau.

I was surprised to see that Martin?s piece has a ?hack-saw? cut job ? something I thought was unique to my piece of Bogou:

I purchased my Bogou several years ago (ex. Cureton Collection) sight-unseen and re-etching and cutting off the hack-saw marks and 'hanging chads' has always been on my to-do list until I read Martin?s article. It is easy to forget that those blemishes can actually help tell the story and human interaction involved with particular specimens. In fact, I think a hacked-up Bogou looks just fine now ?


Martin also reminds us of how delicate and rare -real- fusion crust on an iron is. On Bogou, it is like the thin crust of a croissant and can easily flake off if not handled properly:

Finally, the ?good? side, showing the curvature of the specimen. One can only imagine how impressive a full slice would be:

Martin, I wonder if our specimens shared a jar with the Cureton Collection?


6 Irons Old,

Mike Bandli
