'36 Buick Series 90 interior

[Guest TJOaks]

I have a '36 Buick Limited 90 8-passenger that I am restoring. It is an original car with the exception of the interior. It was recovered years ago with the wrong material. They did not cover over the original fabric so there is no fabric sample or stitch pattern to go by. The car is black (paint code 370) and the interior trim code is 250. Can anyone translate the interior code or know where I could find any interior pictures of a 1936 Limited? It will be a really great car but as the name says, "Limited", I find myself limited on resources for this car.

Any help will be appreciated!
