Original Seating Material

I am looking to acquire old seating material that some of you may have replaced and saved or plan to have replaced on your 20’s closed cars.

I have a 1924, Series 80, 7-Pass Deluxe that is in need of a few stretches of material to make it right. I currently do not wish to use modern fabric.

The original material appears a dull green/brown with a faint blue stripe. When viewing the reverse side, the green appears olive drab and navy (vibrant on that side, wouldn’t you know).

Also, if anyone has any leads to upolsterers who save vintage cloth, that information will be appreciated. Thanks!
