I have made these BD.6113 Packing for Seat Slides (4).
I made them out of 3/8" Baltic Birch plywood, 1-1/2" x 15".
They are found on page 8 of the FHC supplement and page 11 of the DHC supplement, under Floor Panels, not Seats incidentally.
So the question is, what was used to cover them?
Moquette, rexine, leather?
Is there definitive evidence, did it vary from year to year, or is it just trimmer’s opinions or owner’s preferences?
Urs Schmid and Bernard Viart do not mention these.
My Mark V had similar seat packings covered in moquette to match the carpeting, which I am quite certain was original.
