I see a
number of Brahin pieces on eBay and am wondering if
these are legitimately meteorite objects.
Well, it's a little difficult to say "yes" to every possible specimen at any given moment, from so many different dealers, but I can't remember seeing an ebay Brahin offering recently, which appeared to be questionable. Pallasites are so unique in appearance that it would be prohibitively difficult to fabricate or substitute something (which makes the Shirokovsky situation all the more remarkable).
Always a good idea to look for the "IMCA" logo in a meteorite dealer's auction - the International Meteorite Collector's Association is a largely-self-policing organization, and its members are dedicated to authenticity.
