Hi MT, Back in July of 2003, I posted a collection of pics of oriented irons known then as Taza in my Accretion Desk article:
http://www.meteorite-times.com/Back_Links/2003/July/Accretion_Desk.htm I highlighted a couple of fully lipped individuals also wondering how such a feature could form. I believe it was Jim Tobin who suggested that the iron was spinning like a wheel parallel to the direction of travel and the lipping produced a "tire effect" around the surface interior which, as is especially viewable in the specimen I nicknamed "a bowl full of flowlines" seemed to have no directional orientation in the usual way, and in fact, has much in common with the Allende pic you posted.
