Thanks all for the input. Before this subject dies I will share with everyone what I found on the Haartz website.
“In addition to the soft-topping embossings noted, there were other grains used for deck and roof cover fabrics for pre-1940 closed cars.…… (Incidentally, the Tuxedo grain, also known as Box grain, saw use on deck fabric for GM-Fisher Body and Packard cars in the 1930s.)
Unfortunately for the restorer, these grains were not standardized through the industry, nor did users of the coated fabrics exercise care in the terminology, especially in the times before 1950. Even fairly common grains could vary either among sources of embossing tooling, among makers of the resultant coated-fabrics and among leather companies, who also used similar embossing technology.”
It is an informative website I would highly recommend. Per their website, deck fabric is the fabric used on closed car tops.
