On a "for what it's worth" basis:

All of the documentation & pictures I have researched, as well as the original cars I have looked at, show that the original 427 comp and S/C cars (i.e. every one of the 30xx cars) came from England with vinyl-covered seats and a grained, black vinyl-like material glued to the doors and rear bulkhead. They were also carpeted on the transmission tunnel and floors in a wool blend that I doubt was Wilton but looks similar. They did not have the aluminum trim piece around the lower door opening to hold the carpeting in place like the street cars. As for the photo of the seat from 3014, the grain does not look original to me, but the seat may either be worn or heavily treated with some kind of vinyl product.
