I forgot about the TRA handbook, pretty handy reference:
"Dash (fascia) Covering (Including Center Instrument Panel) - The dash on all cars was covered in a thinly backed vinyl to match the trim, including the glovebox door, and on cars up to TS 22014, the center instrument panel. After TS 22014, the center instrument panel was finished in black wrinkle finish paint. Some TR3Bs may have had their centre instument panels covered with vynide that matches the trim or possibly with black vynide."
So that vinyl covering on 3Bs may not be very common.
