Yep, pigskin was only in tan from what I've seen and only on early 2800 cars. My first coupe was a Nevada 2800CSa with pigskin interior- beautiful car.. but I didn't appreciate it in my "youth". My new to me 2800 Sedan (also in Nevada) has some pigskin in it so I'm thinking there's a Nevada color connection here?
Based upon what I am reading in this thread, BMW's pigskin seats were full grain (thanks rsporsche) and evidently had large "open pore" texture throughout. To my untrained eyes, the for-sale seats here appear to be covered in smooth, uniform "top grain." Since there is no specific data regarding durability comparisons between porcine and bovine covers, would they feel any different to the touch?
I can't recall pigskin being used for seat coverings (versus cowhide) by any major auto manufacturer anymore than I can recall pigskin being used for shoes, except for the Hushpuppies brand.
Were other manufacturers known for using pigskin in their interiors?
Is there a generally accepted reason for why the factory chose to favor one material over another? Cost? Availability? Skin size? Cultural sensitivities?
Is it safe to assume that pigskin would have been a secondary choice for leather, presumably as is the case with shoe leather and other "fine" leather furniture? I base this supposition on the notion that, for the most part, "Connolly Leather" (moo) was historically associated with the higher end auto manufactures - for a reason.
