From the photos and the dimensions given, it appears that this is an authentic Be&D....the hardware, studs, interior fabric, metal logo plate, zipper, cell phone pocket, metal feet, sleeper bag, etc. all are the style of the 2007 models. I am making this judgement based on the Garbo satchel that I have that is basically the same bag without all of the "bells and whistles" of this style. I bought the bag directly from Be&D.
I hope your friend enjoys her bag - it's a beauty made with top notch materials and indeed, at a very lovely price.
Hope this helps.
PS - also to make your friend feel more comfortable, I do not know of "fake" Be&D bags that are being made like other designer bags. Be&D is more of a "boutique brand" and thus I do not think it is worth the trouble for counterfitters to make cuz it's not mainstream.
