Hello Mike, Frank and All,

I doubt our pieces of Bogou share a room at the Hotel Cureton. My
piece came from a university collection that likely acquired the
specimen in the early 1970s. I suspect it originally came from either
the Smithsonian or directly from a museum in Africa. I think the
Smithsonian is most likely since that is where a majority of the mass
is housed, as well as the fact that many other small iron samples in
the university collection came with Smithsonian documentation.

I don't know if you have it, but here is the link to Met Bull 25 that
contains the Bogou entry. A wonderful little story.

Best,

Martin

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.

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 ?
