The cloth should be whiskey in color in the Model 90.

I've only seen the copper used on some Model 89 and 19 sets, and these usually appear to be whiskey until you remove the old cloth from the cabinet and find that the "whiskey" is actually faded copper.

Good luck finding any now. Like all of the other popular cloth patterns, neither Radio Grille Cloth Headquarters, Radio Daze or Antique Electronic Supply has any left.
