Thanks Bob. I just ordered a piece of the "Whiskey Rayon" pattern which closely matches the original--just not sure about that amazing coppery metallic sheen in the original threads. I noticed that metallic quality in grille cloth of two old Zeniths I worked on. I wonder what thread they used? Perhaps it isn't made any longer.

There are only a limited number of places to get grille cloth that is similar to original patterns and many patterns have never or are no longer being reproduced.  A list of possible sources can be found here.
