I've worked on ~3 amps from the 50s that have speaker grilles that are basically window-screen or coarse fabric with some sort of fuzzy/furry material applied to it in a pattern.
So, what is this stuff? On at least one of these amps, a lot of it has fallen off, and it has to contribute in some way to the amp's sound by damping the highs and/or loading the speaker slightly.
I'd have no idea how to go about restoring it.
