oil bath air filter material

The fibre material inside the oil bath air filter on my 1947 Clipper is getting pretty thin. I don't know what amount should be in the filter housing but it appears to be only about 2" thick and the filter housing could hold much more I am sure. I have noticed that the carburetor gets wet with the 50 wgt. oil so I assume the filter material is no longer sufficient and is being drawn up through the filtering material. It appears to be something like the material wood fibre "excelsior" used for packing but I doubt that it would withstand being soaked in oil. Does anyone know a suitable source of original or replacement product that could be used to augment what is still in the filter? It would have to be something which I could push up through the holes as the filter cannot be disassembled to access the filter material without grinding spot welds etc.
