Are we talking about the white pencil eraser blocks like one can buy at office supply stores? I have been wracking my brain to find a substitute for the OEM rubber separators that seem to get lost. Just carve out something from the eraser as stock material?
I too realize this is an old thread, but if anyone who's still watching it can confirm that would be great.
Sorry I'm no help with the Beseler drum. But I have Unicolor drums.
