Hi list and Bernd,
the camacite needles or spindles in Taza are very sharp defined and come out
very contrastful after etching. If there are a lot of spindles, they are
often so oriented, that they indeed are imitating a kind of a
"Widmannst?ttern pattern", but not very similar to Dronino.
IVA - that's a good point!!
Take a look again on that slice on ebay. One can clearly see, that it's
composed of three large crystals, wherein the orientation of the "pattern"
shows different orientation - almost the complete left half, then upper part
to the right and bottom right -
seperated well visible by the dark clefts.
Immediately when I saw this slice, Gibeon came in my mind, where also such
composed slices can be found.
(Take f.e. a look in your Buehler, page 120).
Dronino is a real uncommon iron!!
(also from Southern Germany with a perfect sky for catching perseids. Hope
it will last until the maximum)
