For me, conservative as I am, with an oriented meteorite one should reckognize easily, where the front and the back is. I'm still missing a publication, where the aerodynamic processes of sculpturing such oriented shapes are explained - smth like that series for orientation at tektites we had in the meteorite magazine. It would be highly necessary to instruct all these, who praise their specimens as oriented, which have only accidentally similar shapes to an oriented piece (often they haven't even that).
Does somebody knows of such an article, paper, book? My "oriented shapes"-Nininger I donated away..... Buckleboo!
