Perhaps it's sandpaper?

I'm not sure the FocoMat IIc didn't once come with sandpaper -- mine has been
modified into being a 'real' production machine. I've added an Ilford MG500
diffusion head and attached computer pack, making it *much* nicer to use. I
have the condenser head too, in case my heirs want to sell it to a collector.
