Steinway decorative cloth

[BSimon999@AOL.COM]

A customer with a 1881 Steinway upright called me and asked about the type 
and availability of the red material behind the cut-outs on his music desk 
panel.  He wants to replace it because movers stuck their fingers through the 
brittle stuff.

Does anyone know what this material is likely to be? (silk, or mercerized 
cotton, or whatever) and is replacement cloth possible to find?

I have not seen the piano yet.

Thanks for any input.
