Here is a shot of the underside of the bakelite block right now. It's not potted. Could it be somebody put some kind of black stuff back in? It's not soft, however. A pencil tip or fingernail cannot make a mark. One video I saw on youtube showed one of these with a potted end. Maybe the bottom is just gone due to the tar expanding and the bottom was thrown out by the person who did the partial restoration.
