Hi guys,
My car is 1114 and the dash materials are definitely original. The face leather (and also the same for the lower trim section) is a fairly textured leather as shown below.
The dash top is "mouse fur/hair" and it is NOT the same as Alcantera. It has zero "grain" and does appear to be a man-made material. I sourced an almost identical product from orange auto upholstery in LA. I will try to post a photo later of the two materials (old and new) together but I can't at the moment.
