    One can certainly find foam plastic sound _absorbent_ 
material but I am not sure that's what you want. If the 
material is that old it was likely horse-hair felt 
impregnated with something. Such material was common in 
typewriters. Beside having some absorbent property it was 
also a vibration damping material. You may be able to find a 
suitable material at an auto parts store. I have not tried a 
Google search but it will likely find the right kind of 
material.
