here are some photos of original ads
the brochure is the orignal cabriolet convertible sedan one issued by Ford
the newspaper ad is dated June 17,1931 ,introducing both the convertible sedan and slant window cabriolet
both leather and dark brown bedford cloth were offered at the introduction June 17,1931
this is stated in the two introductory ads
the chicago newsletter 6-19-31 lists the dark brown bedford cloth
and in 7-10 1931 it lists the crushed grain leather
BUT in the oct 8 1931 Indianopolis newsletter it states that Deep Brown crushed grain leather TRIM is availible
"this being optional with the Brown Broadcloth upholstry or the Gray Drab material
all this being said
if your going for fine point leather will only be allowed after Oct 1931 how many cars were made after this ,i dont know
